Devices should allow for 3-state signals not to consume current. 2) The signal should be grounded by the host. 3) The signal should be tied to VCC by the host. 4) The mode is required for CompactFlash Storage Cards. 5) The -CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled upon the card in these modes, it should not be left floating by the host in PC Card modes. In these modes, the pin should be connected by the host to PC Card A25 or grounded by the host. 6) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For proper operation in older hosts: while DMA operations are not active, the card shall ignore this signal,including a floating condition 7) Signal usage in True IDE Mode except when Ultra DMA mode protocol is active. 8) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Write is active. 9) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Read is active. 10) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Write is active. 11) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Read is active. 12) Signal usage in PC Card I/O and Memory Mode when Ultra DMA protocol is active. Transcend Information Inc. 5 TS4G~16GCF300 TS4G~16GCF300 Signal Description Signal Name A10 - A00 (PC Card Memory Mode) 300X CompactFlash Card Dir. I Pin Description 8,10,11,12, These address lines along with the -REG signal are used to select the following: 14,15,16,17, The I/O port address registers within the CompactFlash Storage Card , the 18,19,20 memory mapped port address registers within the CompactFlash Storage Card, a byte in the card's information structure and its configuration control and status registers. This signal is the same as the PC Card Memory Mode signal. A10 - A00 (PC Card I/O Mode) A02 - A00 (True IDE Mode) I 18,19,20 In True IDE Mode, only A[02:00] are used to select the one of eight registers in the Task File, the remaining address lines should be grounded by the host. This signal is asserted high, as BVD1 is not supported. BVD1 (PC Card Memory Mode) I/O 46 -STSCHG (PC Card I/O Mode) Status Changed This signal is asserted low to alert the host to changes in the READY and Write Protect states, while the I/O interface is configured. Its use is controlled by the Card Config and Status Register. In the True IDE Mode, this input / output is the Pass Diagnostic signal in the Master / Slave handshake protocol. -PDIAG (True IDE Mode) BVD2 (PC Card Memory Mode) I/O 45 This signal is asserted high, as BVD2 is not supported. -SPKR (PC Card I/O Mode) This line is the Binary Audio output from the card. If the Card does not support the Binary Audio function, this line should be held negated. In the True IDE Mode, this input/output is the Disk Active/Slave Present signal in the Master/Slave handshake protocol. -DASP (True IDE Mode) -CD1, -CD2 (PC Card Memory Mode) O 26,25 These Card Detect pins are connected to ground on the CompactFlash Storage Card. They are used by the host to determine that the CompactFlash Storage Card is fully inserted into its socket. This signal is the same for all modes. -CD1, -CD2 (PC Card I/O Mode) -CD1, -CD2 (True IDE Mode) This signal is the same for all modes. Transcend Information Inc. 6 TS4G~16GCF300 TS4G~16GCF300 Signal Name -CE1, -CE2 (PC Card Memory Mode) Card Enable 300X CompactFlash Card Pin 7,32 Description These input signals are used both to select the card and to indicate to the card whether a byte or a word operation is being performed. -CE2 always accesses the odd byte of the word.-CE1 accesses the even byte or the Odd byte of the word depending on A0 and -CE2. A multiplexing scheme based on A0,-CE1, -CE2 allows 8 bit hosts to access all data on D0-D7. See Table 27, Table 29, Table 31, Table 35, Table 36 and Table 37. This signal is the same as the PC Card Memory Mode signal. Dir. I -CE1, -CE2 (PC Card I/O Mode) Card Enable -CS0, -CS1 (True IDE Mode) In the True IDE Mode, -CS0 is the address range select for the task file registers while -CS1 is used to select the Alternate Status Register and the Device Control Register. While -DMACK is asserted, -CS0 and -CS1 shall be held negated and the width of the transfers shall be 16 bits. -CSEL (PC Card Memory Mode) I 39 This signal is not used for this mode, but should be connected by the host to PC Card A25 or grounded by the host. This signal is not used for this mode, but should be connected by the host to PC Card A25 or grounded by the host. This internally pulled up signal is used to configure this device as a Master or a Slave when configured in the True IDE Mode. When this pin is grounded, this device is configured as a Master. When the pin is open, this device is configured as a Slave. -CSEL (PC Card I/O Mode) -CSEL (True IDE Mode) D15 - D00 (PC Card Memory Mode) I/O 31,30,29,28, These lines carry the Data, Commands and Status information between the host 27,49,48,47, and the controller. D00 is the LSB of the Even Byte of the Word. D08 is the LSB 6,5,4,3,2, of the Odd Byte of the Word. 23, 22, 21 This signal is the same as the PC Card Memory Mode signal. D15 - D00 (PC Card I/O Mode) D15 - D00 (True IDE Mode) In True IDE Mode, all Task File operations occur in byte mode on the low order bus D[7:0] while all data transfers are 16 bit using D[15:0]. GND (PC Card Memory Mode) -- 1,50 Ground. GND (PC Card I/O Mode) This signal is the same for all modes. GND (True IDE Mode) This signal is the same for all modes. Transcend Information Inc. 7 TS4G~16GCF300 TS4G~16GCF300 Signal Name -INPACK (PC Card Memory Mode except Ultra DMA Protocol Active) 300X CompactFlash Card Pin 43 Description This signal is not used in this mode. The Input Acknowledge signal is asserted by the CompactFlash Storage Card when the card is selected and responding to an I/O read cycle at the address that is on the address bus. This signal is used by the host to control the enable of any input data buffers between the CompactFlash Storage Card and the CPU. Hosts that support a single socket per interface logic, such as for Advanced Timing Modes and Ultra DMA operation may ignore the -INPACK signal from the device and manage their input buffers based solely on Card Enable signals. This signal is a DMA Request that is used for DMA data transfers between host and device. It shall be asserted by the device when it is ready to transfer data to or from the host. For Multiword DMA transfers, the direction of data transfer is controlled by -IORD and -IOWR. This signal is used in a handshake manner with (-)DMACK, i.e., the device shall wait until the host asserts (-)DMACK before negating (-)DMARQ, and re-asserting (-)DMARQ if there is more data to transfer. In PCMCIA I/O Mode, the -DMARQ shall be ignored by the host while the host is performing an I/O Read cycle to the device. The host shall not initiate an I/O Read cycle while -DMARQ is asserted by the device. In True IDE Mode, DMARQ shall not be driven when the device is not selected in the Drive-Head register. While a DMA operation is in progress, -CS0 (-CE1)and -CS1 (-CE2) shall be held negated and the width of the transfers shall be 16 bits. If there is no hardware support for True IDE DMA mode in the host, this output signal is not used and should not be connected at the host. In this case, the BIOS must report that DMA mode is not supported by the host so that device drivers will not attempt DMA mode operation. A host that does not support DMA mode and implements both PC Card and True IDE modes of operation need not alter the PC Card mode connections while in True IDE mode as long as this does not prevent proper operation in any mode. Dir. O -INPACK (PC Card I/O Mode except Ultra DMA Protocol Active) Input Acknowledge -DMARQ (PC Card Memory Mode -Ultra DMA Protocol Active) -DMARQ (PC Card I/O Mode -Ultra DMA Protocol Active) DMARQ (True IDE Mode) -IORD (PC Card Memory Mode except Ultra DMA Protocol Active) I 34 This signal is not used in this mode. This is an I/O Read strobe generated by the host. This signal gates I/O data onto the bus from the CompactFlash Storage Card when the card is configured to use the I/O interface. In True IDE Mode, while Ultra DMA mode is not active, this signal has the same function as in PC Card I/O Mode. In all modes when Ultra DMA mode DMA Read is active, this signal is asserted by the host to indicate that the host is ready to receive Ultra DMA data-in bursts. The host may negate - HDMARDY to pause an Ultra DMA transfer. In all modes when Ultra DMA mode DMA Write is active, this signal is the data out strobe generated by the host. Both the rising and falling edge of HSTROBE cause data to be latched by the device. The host may stop generating HSTROBE edges to pause an Ultra DMA data-out burst. -IORD (PC Card I/O Mode except Ultra DMA Protocol Active) -IORD (True IDE Mode - Except Ultra DMA Protocol Active) -HDMARDY (All Modes - Ultra DMA Protocol DMA Read) HSTROBE (All Modes - Ultra DMA Protocol DMA Write) Transcend Information Inc. 8 TS4G~16GCF300 TS4G~16GCF300 Signal Name -IOWR (PC Card Memory Mode- Except Ultra DMA Protocol Active) 300X CompactFlash Card Pin 35 Description This signal is not used in this mode. Dir. I -IOWR (PC Card I/O Mode -Except Ultra DMA Protocol Active) The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the CompactFlash Storage Card controller registers when the CompactFlash Storage Card is configured to use the I/O interface. The clocking shall occur on the negative to positive edge of the signal (trailing edge). -IOWR (True IDE Mode - Except Ultra DMA Protocol Active) In True IDE Mode, while Ultra DMA mode protocol is not active, this signal has the same function as in PC Card I/O Mode. When Ultra DMA mode protocol is supported, this signal must be negated before entering Ultra DMA mode protocol. In All Modes, while Ultra DMA mode protocol is active, the assertion of this signal causes the termination of the Ultra DMA data burst. STOP (All Modes - Ultra DMA Protocol Active) -OE (PC Card Memory Mode) I 9 This is an Output Enable strobe generated by the host interface. It is used to read data from the CompactFlash Storage Card in Memory Mode and to read the CIS and configuration registers. In PC Card I/O Mode, this signal is used to read the CIS and configuration registers. To enable True IDE Mode this input should be grounded by the host. -OE (PC Card I/O Mode) -ATA SEL (True IDE Mode) READY (PC Card Memory Mode) O 37 In Memory Mode, this signal is set high when the CompactFlash Storage Card is ready to accept a new data transfer operation and is held low when the card is busy. At power up and at Reset, the READY signal is held low (busy) until the CompactFlash Storage Card has completed its power up or reset function. No access of any type should be made to the CompactFlash Storage Card during this time. Note, however, that when a card is powered up and used with RESET continuously disconnected or asserted, the Reset function of the RESET pin is disabled. Consequently, the continuous assertion of RESET from the application of power shall not cause the READY signal to remain continuously in the busy state. -IREQ (PC Card I/O Mode) I/O Operation - After the CompactFlash Storage Card Card has been configured for I/O operation, this signal is used as -Interrupt Request. This line is strobed low to generate a pulse mode interrupt or held low for a level mode interrupt. In True IDE Mode signal is the active high Interrupt Request to the host. INTRQ (True IDE Mode) Transcend Information Inc. 9 TS4G~16GCF300 TS4G~16GCF300 Signal Name -REG (PC Card Memory Mode- Except Ultra DMA Protocol Active) 300X CompactFlash Card Pin 44 Description This signal is used during Memory Cycles to distinguish between Common Memory and Register (Attribute) Memory accesses. High for Common Memory, Low for Attribute Memory. In PC Card Memory Mode, when Ultra DMA Protocol is supported by the host and the host has enabled Ultra DMA protocol on the card the, host shall keep the -REG signal negated during the execution of any DMA Command by the device. The signal shall also be active (low) during I/O Cycles when the I/O address is on the Bus. In PC Card I/O Mode, when Ultra DMA Protocol is supported by the host and the host has enabled Ultra DMA protocol on the card the, host shall keep the -REG signal asserted during the execution of any DMA Command by the device. This is a DMA Acknowledge signal that is asserted by the host in response to (-)DMARQ to initiate DMA transfers. In True IDE Mode, while DMA operations are not active, the card shall ignore the (-)DMACK signal, including a floating condition. If DMA operation is not supported by a True IDE Mode only host, this signal should be driven high or connected to VCC by the host. A host that does not support DMA mode and implements both PC Card and True-IDE modes of operation need not alter the PC Card mode connections while in True-IDE mode as long as this does not prevent proper operation all modes. Dir. I Attribute Memory Select -REG (PC Card I/O Mode -Except Ultra DMA Protocol Active) -DMACK (PC Card Memory Mode when Ultra DMA Protocol Active) DMACK (PC Card I/O Mode when Ultra DMA Protocol Active) -DMACK (True IDE Mode) RESET (PC Card Memory Mode) I 41 The CompactFlash Storage Card is Reset when the RESET pin is high with the following important exception: The host may leave the RESET pin open or keep it continually high from the application of power without causing a continuous Reset of the card. Under either of these conditions, the card shall emerge from power-up having completed an initial Reset. The CompactFlash Storage Card is also Reset when the Soft Reset bit in the Card Configuration Option Register is set. RESET (PC Card I/O Mode) This signal is the same as the PC Card Memory Mode signal. -RESET (True IDE Mode) In the True IDE Mode, this input pin is the active low hardware reset from the host. VCC (PC Card Memory Mode) -- 13,38 +5 V, +3.3 V power. VCC (PC Card I/O Mode) This signal is the same for all modes. VCC (True IDE Mode) This signal is the same for all modes. Transcend Information Inc. 10 TS4G~16GCF300 TS4G~16GCF300 Signal Name -VS1 -VS2 (PC Card Memory Mode) 300X CompactFlash Card Pin 33 40 Description Voltage Sense Signals. -VS1 is grounded on the Card and sensed by the Host so that the CompactFlash Storage Card CIS can be read at 3.3 volts and -VS2 is reserved by PCMCIA for a secondary voltage and is not connected on the Card. This signal is the same for all modes. Dir. O -VS1 -VS2 (PC Card I/O Mode) -VS1 -VS2 (True IDE Mode) This signal is the same for all modes. -WAIT (PC Card Memory Mode - Except Ultra DMA Protocol Active) O 42 The -WAIT signal is driven low by the CompactFlash Storage Card to signal the host to delay completion of a memory or I/O cycle that is in progress. This signal is the same as the PC Card Memory Mode signal. -WAIT (PC Card I/O Mode -Except Ultra DMA Protocol Active) IORDY (True IDE Mode - Except Ultra DMA Protocol Active) In True IDE Mode, except in Ultra DMA modes, this output signal may be used as IORDY. In all modes, when Ultra DMA mode DMA Write is active, this signal is asserted by the device during a data burst to indicate that the device is ready to receive Ultra DMA data out bursts. The device may negate -DDMARDY to pause an Ultra DMA transfer. In all modes, when Ultra DMA mode DMA Read is active, this signal is the data in strobe generated by the device. Both the rising and falling edge of DSTROBE cause data to be latched by the host. The device may stop generating DSTROBE edges to pause an Ultra DMA data in burst. -DDMARDY (All Modes - Ultra DMA Write Protocol Active) DSTROBE (All Modes - Ultra DMA Read Protocol Active) -WE (PC Card Memory Mode) I 36 This is a signal driven by the host and used for strobing memory write data to the registers of the CompactFlash Storage Card when the card is configured in the memory interface mode. It is also used for writing the configuration registers. In PC Card I/O Mode, this signal is used for writing the configuration registers. -WE (PC Card I/O Mode) -WE (True IDE Mode) WP (PC Card Memory Mode) Write Protect -IOIS16 (PC Card I/O Mode) O 24 In True IDE Mode, this input signal is not used and should be connected to VCC by the host. Memory Mode - The CompactFlash Storage Card does not have a write protect switch. This signal is held low after the completion of the reset initialization sequence. I/O Operation - When the CompactFlash Storage Card is configured for I/O Operation Pin 24 is used for the -I/O Selected is 16 Bit Port (-IOIS16) function. A Low signal indicates that a 16 bit or odd byte only operation can be performed at the addressed port. In True IDE Mode this output signal is asserted low when this device is expecting a word data transfer cycle. -IOCS16 (True IDE Mode) Transcend Information Inc. 11 TS4G~16GCF300 TS4G~16GCF300 Electrical Specification 300X CompactFlash Card The following tables indicate all D.C.

The socket shall be able to drive at least the following load 10 while meeting all AC timing requirements: (the number of sockets wired in parallel) multiplied by (50 pF with DC current 700 A low state and 150 A high state per socket). 2) Resistor is optional. 3) Status Signals: the socket shall present a load to the card no larger than 50 pF 10 at a DC current of 400 A low state and 100 A high state, including pull-up resistor. The card shall be able to drive at least the following load 10 while meeting all AC timing requirements: 50 pF at a DC current of 400 A low state and 100 A high state. 4) Status Signals: the socket shall present a load to the card no larger than 50 pF 10 at a DC current of 400 A low state and 100 A high state, including pull-up resistor. The card shall be able to drive at least the following load 10 while meeting all AC timing requirements: 50 pF at a DC current of 400 A low state and 100 A high state. 5) Status Signals: the socket shall present a load to the card no larger than 50 pF 10 at a DC current of 400 A low state and 100 A high state, including pull-up resistor. The card shall be able to drive at least the following load 10 while meeting all AC timing requirements: 50 pF at a DC current of 400 A low state and 1100 A high state. 6) BVD2 was not defined in the JEIDA 3.0 release. Systems fully supporting JEIDA release 3 SRAM cards shall pull-up pin 45 (BVD2) to avoid sensing their batteries as "Low." 7) Address Signals: each card shall present a load of no more than 100pF 10 at a DC current of 450A low state and 150A high state. The host shall be able to drive at least the following load 10 while meeting all AC timing requirements: (the number of sockets wired in parallel) multiplied by (100pF with DC current 450A low state and 150A high state per socket). 8) Data Signals: the host and each card shall present a load no larger than 50pF 10 at a DC current of 450A and 150A high state. The host and each card shall be able to drive at least the following load 10 while meeting all AC timing requirements: 100pF with DC current 1.6mA low state and 300A high state. This permits the host to wire two sockets in parallel without derating the card access speeds. 9) Reset Signal: This signal is pulled up to prevent the input from floating when a CFA to PCMCIA adapter is used in a PCMCIA revision 1 host. However, to minimize DC current drain through the pull-up resistor in normal operation the pull-up should be turned off once the Reset signal has been actively driven low by the host. Consequently, the input is specified as an I2Z because the resistor is not necessarily detectable in the input current leakage test. 10) Host and card restrictions for CF Advanced Timing Modes and Ultra DMA modes: Additional Requirements for CF Advanced Timing Modes and Ultra DMA Electrical Requirements for additional required limitations on the implementation of CF Advanced Timing modes and Ultra DMA modes respectively. Additional Requirements for CF Advanced Timing Modes The CF Advanced Timing modes include PC Card I/O and Memory modes that are 100ns or faster, PC Card Ultra DMA modes 3 or above and True IDE PIO Modes 5,6, Multiword DMA Modes 3,4 and True IDE Ultra DMA modes 3 or above. When operating in CF Advanced timing modes, the host shall conform to the following requirements: 1) Only one CF device shall be attached to the CF Bus. 2) The host shall not present a load of more than 40pF to the device for all signals, including any cabling. 3) The maximum cable length is 0.15 m (6 in). The cable length is measured from the card connector to the host controller. 0.46 m (18 in) cables are not supported. 4) The -WAIT and IORDY signals shall be ignored by the host. Devices supporting CF Advanced timing modes shall also support slower timing modes, to ensure operability with systems that do not support CF Advanced timing modes Transcend Information Inc. 16 TS4G~16GCF300 TS4G~16GCF300 Ultra DMA Electrical Requirements Host and Card signal capacitance limits for Ultra DMA operation 300X CompactFlash Card The host interface signal capacitance at the host connector shall be a maximum of 25 pF for each signal as measured at 1 MHz. The card interface signal capacitance at the card connector shall be a maximum of 20 pF for each signal as measured at 1 MHz. Series termination required for Ultra DMA operation Series termination resistors are required at both the host and the card for operation in any of the Ultra DMA modes. Table describes typical values for series termination at the host and the device. Table: Typical Series Termination for Ultra DMA Signal Host Termination Device Termination -IORD (-HDMARDY,HSTROBE) 22 ohm 82 ohm -IOWR (STOP) 22 ohm 82 ohm -CS0, -CS1 33 ohm 82 ohm A00, A01, A02 33 ohm 82 ohm -DMACK 22 ohm 82 ohm D15 through D00 33 ohm 33 ohm DMARQ 82 ohm 22 ohm INTRQ 82 ohm 22 ohm IORDY (-DDMARDY, DSTROBE) 82 ohm 22 ohm -RESET 33 ohm 82 ohm NOTE - Only those signals requiring termination are listed in this table. If a signal is not listed, series termination is not required for operation in an Ultra DMA mode. Shows signals also requiring a pull-up or pull-down resistor at the host. The actual termination values should be selected to compensate for transceiver and trace impedance to match the characteristic cable impedance. Transcend Information Inc. 17 TS4G~16GCF300 TS4G~16GCF300 300X CompactFlash Card Table: Ultra DMA Termination with Pull-up or Pull down Example Printed Circuit Board (PCB) Trace Requirements for Ultra DMA On any PCB for a host or device supporting Ultra DMA: The longest D[15:00] trace shall be no more than 0.5" longer than either STROBE trace as measured from the IC pin to the connector. The shortest D[15:00] trace shall be no more than 0.5" shorter than either STROBE trace as measured from the IC pin to the connector. Ultra DMA Mode Cabling Requirement Operation in Ultra DMA mode requires a crosstalk suppressing cable. The cable shall have a grounded line between each signal line. For True IDE mode operation using a cable with IDE (ATA) type 40 pin connectors it is recommended that the host sense the cable type using the method described in the ANSI INCITS 361-2002 AT Attachment - 6 standard, to prevent use of Ultra DMA with a 40 conductor cable.

The maximum load on -IOCS16 is 1 LSTTL with a 50 pF (40pF below 120nsec Cycle Time) total load. All times are in nanoseconds. Minimum time from -IORDY high to -IORD high is 0 nsec, but minimum -IORD width shall still be met. 1) t0 is the minimum total cycle time, t2 is the minimum command active time, and t2i is the minimum command recovery time or command inactive time. The actual cycle time equals the sum of the actual command active time and the actual command inactive time. The three timing requirements of t0, t2, and t2i shall be met. The minimum total cycle time requirement is greater than the sum of t2 and t2i. This means a host implementation can lengthen either or both t2 or t2i to ensure that t0 is equal to or greater than the value reported in the device's identify device data. A CompactFlash Storage Card implementation shall support any legal host implementation. 2) This parameter specifies the time from the negation edge of -IORD to the time that the data bus is no longer driven by the CompactFlash Storage Card (tri-state). 3) The delay from the activation of -IORD or -IOWR until the state of IORDY is first sampled. If IORDY is inactive then the host shall wait until IORDY is active before the PIO cycle can be completed. If the CompactFlash Storage Card is not driving IORDY negated at tA after the activation of -IORD or -IOWR, then t5 shall be met and tRD is not applicable. If the CompactFlash Storage Card is driving IORDY negated at the time tA after the activation of -IORD or -IOWR, then tRD shall be met and t5 is not applicable. 4) t7 and t8 apply only to modes 0, 1 and 2. For other modes, this signal is not valid. 5) IORDY is not supported in this mode.

Several signal lines are redefined to provide different functions during an Ultra DMA data burst. These lines assume their UDMA definitions when: 1 2 3 4 an Ultra DMA mode is selected, and a host issues a READ DMA, or a WRITE DMA command requiring data transfer, and the device asserts (-)DMARQ, and the host asserts (-)DMACK. These signal lines revert back to the definitions used for non-Ultra DMA transfers upon the negation of -DMACK by the host at the termination of an Ultra DMA data burst. With the Ultra DMA protocol, the STROBE signal that latches data from D[15:00] is generated by the same agent (either host or device) that drives the data onto the bus. Ownership of D[15:00] and this data strobe signal are given either to the device during an Ultra DMA data-in burst or to the host for an Ultra DMA data-out burst. During an Ultra DMA data burst a sender shall always drive data onto the bus, and, after a sufficient time to allow for propagation delay, cable settling, and setup time, the sender shall generate a STROBE edge to latch the data. Both edges of STROBE are used for data transfers so that the frequency of STROBE is limited to the same frequency as the data. Words in the IDENTIFY DEVICE data indicate support of the Ultra DMA feature and the Ultra DMA modes the device is capable of supporting. The Set transfer mode subcommand in the SET FEATURES command shall be used by a host to Transcend Information Inc. 28 TS4G~16GCF300 TS4G~16GCF300 300X CompactFlash Card select the Ultra DMA mode at which the system operates. The Ultra DMA mode selected by a host shall be less than or equal to the fastest mode of which the device is capable. Only one Ultra DMA mode shall be selected at any given time. All timing requirements for a selected Ultra DMA mode shall be satisfied. Devices supporting any Ultra DMA mode shall also support all slower Ultra DMA modes. An Ultra DMA capable device shall retain the previously selected Ultra DMA mode after executing a software reset sequence or the sequence caused by receipt of a DEVICE RESET command if a SET FEATURES disable reverting to defaults command has been issued. The device may revert to a Multiword DMA mode if a SET FEATURES enable reverting to default has been issued. An Ultra DMA capable device shall clear any previously selected Ultra DMA mode and revert to the default non-Ultra DMA modes after executing a power-on or hardware reset. Both the host and device perform a CRC function during an Ultra DMA data burst. At the end of an Ultra DMA data burst the host sends its CRC data to the device. The device compares its CRC data to the data sent from the host. If the two values do not match, the device reports an error in the error register. If an error occurs during one or more Ultra DMA data bursts for any one command, the device shall report the first error that occurred. If the device detects that a CRC error has occurred before data transfer for the command is complete, the device may complete the transfer and report the error or abort the command and report the error. NOTE -If a data transfer is terminated before completion, the assertion of INTRQ should be passed through to the host software driver regardless of whether all data requested by the command has been transferred.

Due to reflections on the cable, these timing measurements are not valid in a normally functioning system. 4)For all modes the parameter tZIORDY may be greater than tENV due to the fact that the host has a pull-up on IORDY- giving it a known state when released. 5)The parameters tDS, and tDH for mode 5 are defined for a recipient at the end of the cable only in a configuration with a single device located at the end of the cable. This could result in the minimum values for tDS and tDH for mode 5 at the middle connector being 3.0 and 3.9 ns respectively.

When a 16 bit accessible port is addressed, the signal -IOIS16 is asserted by the CompactFlash Storage. Otherwise, the -IOIS16 signal is de-asserted. When a 16 bit transfer is attempted, and the -IOIS16 signal is not asserted by the CompactFlash Storage, the system shall generate a pair of 8 bit references to access the word`s even byte and odd byte. The CompactFlash Storage Card permits both 8 and 16 bit accesses to all of its I/O addresses, so -IOIS16 is asserted for all addresses to which the CompactFlash Storage responds. The CompactFlash Storage Card may request the host to extend the length of an input cycle until data is ready by asserting the -WAIT signal at the start of the cycle.

The CompactFlash Storage Card is configured in this mode only when the -OE input signal is grounded by the host during the power off to power on cycle. Optionally, CompactFlash Storage Cards may support the following optional detection methods: 1. The card is permitted to monitor the -OE (-ATA SEL) signal at any time(s) and switch to PCMCIA mode upon detecting a high level on the pin. 2. The card is permitted to re-arbitrate the interface mode determination following a transition of the (-)RESET pin. 3. The card is permitted to monitor the -OE (-ATA SEL) signal at any time(s) and switch to True IDE mode upon detection of a continuous low level on pin for an extended period of time. Table: True IDE Mode I/O Function defines the function of the operations for the True IDE Mode. Transcend Information Inc. 44 TS4G~16GCF300 TS4G~16GCF300 300X CompactFlash Card Host Configuration Requirements for Master/Slave or New Timing Modes The CF Advanced Timing modes include PCMCIA PC Card style I/O modes that are faster than the original 250 ns cycle time. These modes are not supported by the PCMCIA PC Card specification nor CF by cards based on revisions of the CF specification before Revision 3.0. Hosts shall ensure that all cards accessed through a common electrical interface are capable of operation at the desired, faster than 250 ns, I/O mode before configuring the interface for that I/O mode. Advanced Timing modes are PCMCIA PC Card style I/O modes that are 100 ns or faster, PC Card Memory modes that are 100ns or faster, True IDE PIO Modes 5,6 and Multiword DMA Modes 3,4. These modes are permitted to be used only when a single card is present and the host and card are connected directly, without a cable exceeding 0.15m in length. Consequently, the host shall not configure a card into an Advanced Timing Mode if two cards are sharing I/O lines, as in Master/Slave operation, nor if it is constructed such that a cable exceeding 0.15 meters is required to connect the host to the card. The load presented to the Host by cards supporting Ultra DMA is more controlled than that presented by other CompactFlash cards. Therefore, the use of a card that does not support Ultra DMA in a Master/Slave arrangement with a Ultra DMA card can affect the critical timing of the Ultra DMA transfers. The host shall not configure a card into Ultra DMA mode when a card not supporting Ultra DMA is also present on the same interface When the use of two cards on an interface is otherwise permitted, the host may use any mode that is supported by both cards, but to achieve maximum performance it should use its highest performance mode that is also supported by both cards. Metaformat Overview The goal of the Metaformat is to describe the requirements and capabilities of the CompactFlash Storage Card as thoroughly as possible. This includes describing the power requirements, IO requirements, memory requirements, manufacturer information and details about the services provided. Table: Sample Device Info Tuple Information for Extended Speeds Note: The value "1" defined for D3 of the N+0 words indicates that no write-protect switch controls writing the ATA registers. The value "0" defined for D7 in the N+2 words indicates that there is not more than a single speed extension byte. Transcend Information Inc. 45 TS4G~16GCF300 TS4G~16GCF300 CF-ATA Drive Register Set Definition and Protocol 300X CompactFlash Card The CompactFlash Storage Card can be configured as a high performance I/O device through: a) The standard PC-AT disk I/O address spaces 1F0h-1F7h, 3F6h-3F7h (primary) or 170h- 177h, 376h-377h (secondary) with IRQ 14 (or other available IRQ). b) Any system decoded 16 byte I/O block using any available IRQ. c) Memory space. The communication to or from the CompactFlash Storage Card is done using the Task File registers, which provide all the necessary registers for control and status information related to the storage medium. The PCMCIA interface connects peripherals to the host using four register mapping methods. Table 39 is a detailed description of these methods: Transcend Information Inc. 46 TS4G~16GCF300 TS4G~16GCF300 I/O Primary and Secondary Address Configurations Table: Primary and Secondary I/O Decoding 300X CompactFlash Card Transcend Information Inc. 47 TS4G~16GCF300 TS4G~16GCF300 Contiguous I/O Mapped Addressing 300X CompactFlash Card When the system decodes a contiguous block of I/O registers to select the CompactFlash Storage Card, the registers are accessed in the block of I/O space decoded by the system as follows: Table: Contiguous I/O Decoding Transcend Information Inc. 48 TS4G~16GCF300 TS4G~16GCF300 Memory Mapped Addressing 300X CompactFlash Card When the CompactFlash Storage Card registers are accessed via memory references, the registers appear in the common memory space window: 0-2K bytes as follows: True IDE Mode Addressing When the CompactFlash Storage Card is configured in the True IDE Mode, the I/O decoding is as follows: Transcend Information Inc. 49 TS4G~16GCF300 TS4G~16GCF300 CF-ATA Registers 300X CompactFlash Card The following section describes the hardware registers used by the host software to issue commands to the CompactFlash device. These registers are often collectively referred to as the "task file." Data Register (Address - 1F0h[170h];Offset 0,8,9) The Data Register is a 16 bit register, and it is used to transfer data blocks between the CompactFlash Storage Card data buffer and the Host. This register overlaps the Error Register. Error Register (Address - 1F1h[171h]; Offset 1, 0Dh Read Only) This register contains additional information about the source of an error when an error is indicated in bit 0 of the Status register. This register is also accessed in PC Card Modes on data bits D15-D8 during a read operation to offset 0 with -CE2 low and -CE1 high. Bit 7 (BBK/ICRC): this bit is set when a Bad Block is detected. This bit is also set when an interface CRC error is detected in True IDE Ultra DMA modes of operation. Bit 6 (UNC): this bit is set when an Uncorrectable Error is encountered. Bit 5: this bit is 0. Bit 4 (IDNF): the requested sector ID is in error or cannot be found. Bit 3: this bit is 0. Bit 2 (Abort) This bit is set if the command has been aborted because of a CompactFlash Storage Card status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued. Bit 1 This bit is 0. Bit 0 (AMNF) This bit is set in case of a general error. Transcend Information Inc. 50 TS4G~16GCF300 TS4G~16GCF300 300X CompactFlash Card Feature Register (Address - 1F1h[171h]; Offset 1, 0Dh Write Only) This register provides information regarding features of the CompactFlash Storage Card that the host can utilize. This register is also accessed in PC Card modes on data bits D15-D8 during a write operation to Offset 0 with -CE2 low and -CE1 high. Sector Count Register (Address - 1F2h[172h]; Offset 2) This register contains the numbers of sectors of data requested to be transferred on a read or write operation between the host and the CompactFlash Storage Card. If the value in this register is zero, a count of 256 sectors is specified. If the command was successful, this register is zero at command completion. If not successfully completed, the register contains the number of sectors that need to be transferred in order to complete the request. Sector Number (LBA 7-0) Register (Address - 1F3h[173h]; Offset 3) This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any CompactFlash Storage Card data access for the subsequent command. 6.1.5.5 Cylinder Low (LBA 15-8) Register (Address - 1F4h[174h]; Offset 4) This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of the Logical Block Address. Cylinder High (LBA 23-16) Register (Address - 1F5h[175h]; Offset 5) This register contains the high order bits of the starting cylinder address or bits 23-16 of the Logical Block Address. Drive/Head (LBA 27-24) Register (Address 1F6h[176h]; Offset 6) The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing instead of cylinder/head/sector addressing. Bit 7: this bit is specified as 1 for backward compatibility reasons. It is intended that this bit will become obsolete in a future revision of the specification. This bit is ignored by some controllers in some commands. Bit 6: LBA is a flag to select either Cylinder/Head/Sector (CHS) or Logical Block Address Mode (LBA). When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block Address is selected. In Logical Block Mode, the Logical Block Address is interpreted as follows: LBA7-LBA0: Sector Number Register D7-D0. LBA15-LBA8: Cylinder Low Register D7-D0. LBA23-LBA16: Cylinder High Register D7-D0. LBA27-LBA24: Drive/Head Register bits HS3-HS0. Bit 5: this bit is specified as 1 for backward compatibility reasons. It is intended that this bit will become obsolete in a future revisions of the specification. This bit is ignored by some controllers in some commands. Bit 4 (DRV): DRV is the drive number. When DRV=0, drive (card) 0 is selected. When DRV=1, drive (card) 1 is selected. Setting this bit to 1 is obsolete in PCMCIA modes of operation. If the obsolete functionality is support by a CF Storage Card, the CompactFlash Storage Card is set to be Card 0 or 1 using the copy field (Drive #) of the PCMCIA Socket & Copy configuration register. Transcend Information Inc. 51 TS4G~16GCF300 TS4G~16GCF300 300X CompactFlash Card Bit 3 (HS3): when operating in the Cylinder, Head, Sector mode, this is bit 3 of the head number. It is Bit 27 in the Logical Block Address mode. Bit 2 (HS2): when operating in the Cylinder, Head, Sector mode, this is bit 2 of the head number. It is Bit 26 in the Logical Block Address mode. Bit 1 (HS1): when operating in the Cylinder, Head, Sector mode, this is bit 1 of the head number. It is Bit 25 in the Logical Block Address mode. Bit 0 (HS0): when operating in the Cylinder, Head, Sector mode, this is bit 0 of the head number. It is Bit 24 in the Logical Block Address mode. Status & Alternate Status Registers (Address 1F7h[177h]&3F6h[376h]; Offsets 7 & Eh) These registers return the CompactFlash Storage Card status when read by the host. Reading the Status register does clear a pending interrupt while reading the Auxiliary Status register does not. The status bits are described as follows: Bit 7 (BUSY): the busy bit is set when the CompactFlash Storage Card has access to the command buffer and registers and the host is locked out from accessing the command register and buffer. No other bits in this register are valid when this bit is set to a 1. During the data transfer of DMA commands, the Card shall not assert DMARQ unless either the BUSY bit, the DRQ bit, or both are set to one. Bit 6 (RDY): RDY indicates whether the device is capable of performing CompactFlash Storage Card operations. This bit is cleared at power up and remains cleared until the CompactFlash Storage Card is ready to accept a command. Bit 5 (DWF): This bit, if set, indicates a write fault has occurred. Bit 4 (DSC): This bit is set when the CompactFlash Storage Card is ready. Bit 3 (DRQ): The Data Request is set when the CompactFlash Storage Card requires that information be transferred either to or from the host through the Data register. During the data transfer of DMA commands, the Card shall not assert DMARQ unless either the BUSY bit, the DRQ bit, or both are set to one. Bit 2 (CORR): This bit is set when a Correctable data error has been encountered and the data has been corrected. This condition does not terminate a multi-sector read operation. Bit 1 (IDX): This bit is always set to 0. Bit 0 (ERR): This bit is set when the previous command has ended in some type of error. The bits in the Error register contain additional information describing the error. It is recommended that media access commands (such as Read Sectors and Write Sectors) that end with an error condition should have the address of the first sector in error in the command block registers. Transcend Information Inc. 52 TS4G~16GCF300 TS4G~16GCF300 Device Control Register (Address - 3F6h[376h]; Offset Eh) 300X CompactFlash Card This register is used to control the CompactFlash Storage Card interrupt request and to issue an ATA soft reset to the card. This register can be written even if the device is BUSY. The bits are defined as follows: Bit 7: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0. Bit 6: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0. Bit 5: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0. Bit 4: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0. Bit 3: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0. Bit 2 (SW Rst): this bit is set to 1 in order to force the CompactFlash Storage Card to perform an AT Disk controller Soft Reset operation. This does not change the PCMCIA Card Configuration Registers as a hardware Reset does. The Card remains in Reset until this bit is reset to `0.' Bit 1 (-IEn): the Interrupt Enable bit enables interrupts when the bit is 0. When the bit is 1, interrupts from the CompactFlash Storage Card are disabled. This bit also controls the Int bit in the Configuration and Status Register. This bit is set to 0 at power on and Reset. Bit 0: this bit is ignored by the CompactFlash Storage Card. Transcend Information Inc. 53 TS4G~16GCF300 TS4G~16GCF300 Card (Drive) Address Register (Address 3F7h[377h]; Offset Fh) 300X CompactFlash Card This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not be mapped into the host's I/O space because of potential conflicts on Bit 7. Bit 7: this bit is unknown. Implementation Note: Conflicts may occur on the host data bus when this bit is provided by a Floppy Disk Controller operating at the same addresses as the CompactFlash Storage Card. Following are some possible solutions to this problem for the PCMCIA implementation: 1) Locate the CompactFlash Storage Card at a non-conflicting address, i.e. Secondary address (377) or in an independently decoded Address Space when a Floppy Disk Controller is located at the Primary addresses. 2) Do not install a Floppy and a CompactFlash Storage Card in the system at the same time. 3) Implement a socket adapter that can be programmed to (conditionally) tri-state D7 of I/0 address 3F7h/377h when a CompactFlash Storage Card is installed and conversely to tristate D6-D0 of I/O address 3F7h/377h when a floppy controller is installed. 4) Do not use the CompactFlash Storage Card's Drive Address register. This may be accomplished by either a) If possible, program the host adapter to enable only I/O addresses 1F0h-1F7h, 3F6h (or 170h-177h, 176h) to the CompactFlash Storage Card or b) if provided use an additional Primary / Secondary configuration in the CompactFlash Storage Card which does not respond to accesses to I/O locations 3F7h and 377h. With either of these implementations, the host software shall not attempt to use information in the Drive Address Register. Bit 6 (-WTG): this bit is 0 when a write operation is in progress; otherwise, it is 1. Bit 5 (-HS3): this bit is the negation of bit 3 in the Drive/Head register. Bit 4 (-HS2): this bit is the negation of bit 2 in the Drive/Head register. Bit 3 (-HS1): this bit is the negation of bit 1 in the Drive/Head register. Bit 2 (-HS0): this bit is the negation of bit 0 in the Drive/Head register. Bit 1 (-nDS1): this bit is 0 when drive 1 is active and selected. Bit 0 (-nDS0): this bit is 0 when the drive 0 is active and selected.

When Word 0 of the Identify drive information is 848Ah then the device is a CompactFlash Storage Card and complies with the CFA specification and CFA command set. It is recommended that PCMCIA modes of operation report only the 848Ah value as they are always intended as removable devices. Bits 15-0: CF Standard Configuration Value Word 0 is 848Ah. This is the recommended value of Word 0. Some operating systems require Bit 6 of Word 0 to be set to 1 (Non-removable device) to use the card as the root storage device. The Card must be the root storage device when a host completely replaces conventional disk storage with a CompactFlash Card in True IDE mode. To support this requirement and provide capability for any future removable media Cards, alternatehandling of Word 0 is permitted. Bits 15-0: CF Preferred Alternate Configuration Values 044Ah: This is the alternate value of Word 0 turns on ATA device and turns off Removable Media and Removable Device while preserving all Retired bits in the word. 0040h: This is the alternate value of Word 0 turns on ATA device and turns off Removable Media and Removable Device while zeroing all Retired bits in the word Bit 15-12: Configuration Flag If bits 15:12 are set to 8h then Word 0 shall be 848Ah. If bits 15:12 are set to 0h then Bits 11:0 are set using the definitions below and the Card is required to support for the CFA command set and report that in bit 2 of Word 83. Bit 15:12 values other than 8h and 0h are prohibited. Bits 11-8: Retired These bits have retired ATA bit definitions. It is recommended that the value of these bits be either the preferred value of 0h or the value of 4h that preserves the corresponding bits from the 848Ah CF signature value. Bit 7: Removable Media Device If Bit 7 is set to 1, the Card contains media that can be removed during Card operation. If Bit 7 is set to 0, the Card contains nonremovable media. Bit 6: Not Removable Controller and/or Device Alert! This bit will be considered for obsolescence in a future revision of this standard. If Bit 6 is set to 1, the Card is intended to be nonremovable during operation. If Bit 6 is set to 0, the Card is intended to be removable during operation. Bits 5-0: Retired/Reserved Alert! Bit 2 will be considered for definition in a future revision of this standard and shall be 0 at this time. Bits 5-1 have retired ATA bit definitions. Bit 2 shall be 0.
