| Freescale Semiconductor, Inc. White Paper MCM69C233WP/D Rev. 2, 1/2003 MPC8260 PowerQUICC IITM to CAM Interfacing - MCM69C233 Freescale Semiconductor, Inc... Eric Jackson Technical Marketing, NCSD Networking & Computing Systems Group The purpose of this document is to provide the designer a hardware method of interfacing the Motorola MPC8260 PowerQUICC IITM Integrated Communications Processor with the MCM69C233 Motorola Flexible Content Addressable Memory (CAM). The following topics are addressed: Topic Section 1, "MPC8260 PowerQUICC IITM" Section 2, "Motorola Content Addressable Memories (CAMs)" Section 3, "CAM Interface" Section 4, "MPC8260 Register Programming" Section 5, "References" Page 1 1 2 4 12 1 MPC8260 PowerQUICC IITM Motorola's PowerQUICC IITM processor family is the next generation of Motorola's leading PowerQUICC line of integrated communication processors. The MPC8260 integrates two main components, the embedded MPC603e G2 core and the Communications Processor Module (CPM). The CPM simultaneously supports three fast serial communications controllers (FCCs), two multichannel controllers (MCCs), four serial communications controllers (SCCs), two serial management controllers (SMCs), one serial peripheral interface (SPI), and one I2C interface. 2 Motorola Content Addressable Memories (CAMs) The MCM69C233 is a flexible content addressable memory (CAM) that can contain 4096 entries of 64 bits. It is implemented with standard 4-transistor SRAM cells. The widths of the match field and the output field are programmable. At 66 MHz, the match time is designed to be less than or equal to 210 nanoseconds. As a result, the Motorola CAM is well suited for datacom applications such as Virtual Path Identifier/Virtual Circuit Identifier (VCI/VPI) translation in ATM switches up to OC12 (622 Mbps) data rates and Media Access Control (MAC) address lookup in Ethernet/Fast Ethernet bridges. The CAM is also well suited for fully associative disk drive cache and RAID applications. The match request rate of the MCM69C233 is user defined with a trade-off between the match request rate and the rate of new entries added to the CAM.

CAM Interface CAM Interface 3 CAM Interface The CAM consists of two independent ports: the control port and the match port. They have different functionality and control requirements. The MPC8260 local bus asserts one unique chip select for control port access and another for the match port. Because the MPC8260 is only able to assert one chip select per memory bank access, the MPC8260 accesses one CAM port at a time; the CAM control port and match port cannot be selected simultaneously. Also note on the MPC8260, some functions are multiplexed with other functions on the same pins. Particularly, on some pins, there are SDRAM signals that reside with signals that are used in the MPC8260/CAM interface. Therefore for this interface, SDRAM cannot be used on the local bus along with the CAM. 3.1 Control Port Interfacing Using the MPC8260 GPCM Freescale Semiconductor, Inc... The CAM control port is an asynchronous 16-bit read/write port. The control port signals consist of A2-A0 (Address), SEL (Select), IRQ (Interrupt), DTACK (Data Acknowledgement), WE (Write Enable), and RESET. The MPC8260 can reset the CAM in software, as the RESET input of the CAM is driven by the hardware reset of the MPC8260. For write transactions, the CAM address and data value should be valid, and the WE should be low when the SEL signal is asserted to begin a write cycle. Address, WE, and SEL signal values should be held until the CAM asserts the DTACK signal to end the write cycle. Note however, that DTACK will not be used in this application and is pulled up with a 1k resistor. The MPC8260 has an internal signal that will end the write transaction. See the Option Register setting in section 4.1 for further details. For read transactions, the address value should be valid and the WE signal should be high when SEL is asserted. Both signals (address, WE, and SEL) should hold their values until the CAM asserts the DTACK signal to end the read cycle. Again, as in the likewise manner of the write sequence, DTACK will not be used to end the read transaction. This memory controller chip behavior can be accomplished via the MPC8260 Memory Controller's General Purpose Chip Select Machine (GPCM). The GPCM allows flexible interfacing between the MPC8260, SRAM, EPROM, flash EPROM, ROM devices and external peripherals. The table below lists the interface signals of the GPCM. Table 1. GPCM Interface Signals 60x Bus CS [0-11] WE[0-7] OE PGTA BCTLx LWE[0-3] LOE LGTA LWR Local Bus Comments Device select Write enables for write cycles Output enables for read cycles Transaction Termination Data Buffer Controls/Local Write-Read From the table, GPCM signals can be generated either on the 60x bus or the local bus. For this document, the MPC8260/CAM control port interfacing will take place on the local bus. The Write enable (LWE[0-3]) and the Transaction Termination signal (LGTA) will not be used. A device select from the MPC8260, CS[1], functions as the CAM SEL while the LWR acts as the CAM WE. The control port is only accessible through 16-bit accesses. Therefore, the CAM address lines A[2:0] will map to the MPC8260 address lines A[28:30] (Each byte of data within the MPC8260 addressing TM to CAM Interfacing - MCM69C233 2 MPC8260 PowerQUICC II MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. CAM Interface scheme has a unique address. Since data transactions will occur on 16-bit intervals [two bytes], A[31] of the MPC8260 address will not be used). The CAM control port data bus (DQ[15:0]) will connect to the MPC8260's local data bus LCL_D[0-15]. The CAM also includes the IRQ signal that can optionally alert the user of certain conditions within the CAM. For this demonstration, IRQ is not used and is pulled up by means of a 1k resistor. 3.2 Match Port Interfacing Using the MPC8260 UPM The CAM match port is synchronous to the input clock (K). The match port is 32 bits wide with read/write capability. Accesses to the match port from the MPC8260 consist of a write transaction followed by a read. The write cycle drives match data into the CAM. This data is latched in when the CAM LH/SM (Latch High/Start Match) signal asserts. The completion of a match search is indicated with the CAM MC (Match Complete) asserting. If a match is found, MS (Match Successful) asserts. The MPC8260 performs a read cycle with data being driven by the CAM with the CAM output enable, G. The MPC8260 Memory Controller's User-Programmable Machine (UPM) will be mapped to the match port of the CAM. The UPM provides flexible interfaces to a wide array of memory devices. The heart of the UPM is the programmable internal-memory RAM array. Each 64-bit word, which is programmed by the user, specifies the signal values for a given clock cycle that are driven on the external memory pins. The table below lists the interface signals of the UPM: Table 2. UPM Interface Signals 60x Bus CS[0-11] PBS(0-7) PGPL_0 PGPL_1 PGPL_2 PGPL_3 PGPL_4/UPWAIT PGPL_5 LBS(0-3) LGPL_0 LGPL_1 LGPL_2 LGPL_3 LGPL_4/UPWAIT LGPL_5 Local Bus Comments Device select Byte Select General-purpose line 0 General-purpose line 1 General-purpose line 2 General-purpose line 3 General-purpose line 4/UPM WAIT General-purpose line 5 Freescale Semiconductor, Inc... From Table 2, UPM signals can be generated either on the 60x bus or the local bus. For this document, the MPC8260/CAM match port interfacing will take place on the local bus. The UPM's CS[2] and LGPL[5] signals are mapped to the CAM LH/SM and G signals, respectively. The UPM will be programmed to assert CS[2] (LH/SM) during write cycles and LGPL[5] (G) during read cycles. The CAM MC signal (pulled up through a 1k resistor) is mapped to the UPM LGPL_4/UPWAIT pin. During a write cycle on the CAM match port, MC deasserts and goes into a high state. This in turn, asserts the UPM UPWAIT signal (this is an active high signal). When UPWAIT is active, the current transaction is frozen until UPWAIT is deasserted (a low state); this occurs when the match algorithm completes and MC enters a low state. All match data written from the MPC8260 will be 32-bit operands; all return data from the CAM will be 32-bit operands. Thereby, the byte select signals (LBS[x]) will not be used. For applications such as Ethernet or ATM, the MPC8260 requires an indication if a match attempt was either successful or not successful. The MPC8260 checks the msb (LCL_D[0]) of the returned data. If the bit is cleared, the data is accepted. If the bit is set, the data is rejected. Therefore, the CAM MS signal (pulled high) will accommodate this requirement. The CAM LL (latch low) signal is needed if the match data MOTOROLA MPC8260 PowerQUICC II TM to CAM Interfacing - MCM69C233 3 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. MPC8260 Register Programming MPC8260 Register Programming written to the CAM requires more than one 32-bit write transaction (for example, if the input match data were 48 bits wide, LL would latch in the lower 16 bits; then, LHSM would latch in the higher 32 bits). For purposes of this document, LL is pulled high and not used. The 32-bit CAM data bus, MQ[31:0], is mapped to the MPC8260 local data bus, LCL_D[0-31].

Figure 1. MPC8260/CAM Interface 4 MPC8260 Register Programming In order to utilize the MPC8260's GPCM and the UPM, two registers in the MPC8260 must be programmed: the base register and the option register. The base registers (BR0-BR11) hold information 4 MPC8260 PowerQUICC II TM to CAM Interfacing - MCM69C233 MOTOROLA For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. MPC8260 Register Programming such as the base address of the memory peripheral (the CAM), the memory attributes, and the selection of the machine handling the memory accesses. The option registers (OP0-OP11) define the size of the memory banks and other access attributes that are depending on the machine selected. 4.1 CAM Control Port Access To select the GPCM to handle accesses to the CAM control port, the base and option registers (BR1 and OR1) should be programmed with the following attributes: Table 3. Base Register (BR1) Bits 0-16 Name BA PS DECC WP MS Description Sets the base address for the CAM's control port Reserved, should be cleared Port Size- Since the CAM control port is 16 bits wide, these two bits should have a value of 10 Data error correction and checking- This feature will not be used. Thereby it is disabled with bit value 00 Write Protect- Can be used for write protection within the address range of BR. For this application R/W capability is needed.

For the control port, the assertion of the chip select will be one quarter of a clock after the address is valid. Thereby, set these bits to 10 Reserved, should be cleared 23 - MOTOROLA MPC8260 PowerQUICC II TM to CAM Interfacing - MCM69C233 5 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.

Each word in the array provides bits that allow a memory access to be controlled with a resolution of up to one quarter of the external bus clock period on the byte-select (BSx) and chip select (CSx) lines. These words also control the behavior of the general-purpose line (GPLx). In order to program these words in to the UPM RAM array, additional registers, the Machine A/B/C Mode register (MxMR) and the Memory Data register (MDR), must also be configured. The MxMR controls the execution of the UPM. The MDR contains data that is written to or read from the RAM array for WRITE or READ commands. Note that the MDR must be set up before issuing a write command to the UPM. To write words into the UPM RAM array: Table 7. Machine A Mode Register Bits 0 1 2-3 4 5-7 Name BSEL RFEN OP AMx Description Bus select- Assigns banks using the UPM to the 60x or Local bus. Since the CAM is on the local bus, set this bit to 1 Refresh enable- Allows refresh services. This will not be used, so set this bit to 0 Command Opcode- To write words (to program) into the array, set these bits to 01. For normal operations, set these bits to 00 Reserved, should be cleared Address Multiplex size- Address multiplexing is not used.

Therefore, the value for MxMR (for this application, MAMR): MAMR = 1001 0000 0000 0100 0000 0000 00xx xxxx where "xx xxxx" is the Machine Address. After the MAMR is set (with the OP field set to 01), RAM words need to be programmed into the RAM array. Only single-beat read and single-beat write patterns are used. Burst, refresh, and exception patterns are not used. For the 66 MHz bus, the following UPM RAM words should be programmed: Single-beat readsFFFFDC00 FFFFDC00 FFFFC805 Single-beat write0FFFC000 FFFFC005 Each time a word is written into the RAM array, the MAD (bits 26-31 of the MxMR) automatically increments. For the above UPM RAM single-beat read patterns, the MxMR will only need to be configured once with the MAD bits set to the address of the first single-beat read (0x00)--the subsequent patterns will be written in consecutive Single-beat read address locations. However, the MxMR will need to be reconfigured for the different MAD pertaining to the first single-beat write pattern (0x18). 4.4 CAM Register Configuration There are three types of registers accessible through the CAM control port: the I/O registers, the operation register, and the results/condition code registers. Each register is 16 bits in length. Data is written into the I/O registers followed by a command code written into the operation register. The results/condition registers alert the user when certain conditions occur or the user may set interrupts when certain conditions occur.

MPC8260 Register Programming Before basic operations of the CAM can begin, there are some start-up functions that must be performed. First the match width and output width must be determined by issuing the SET GLOBAL MASK REGISTER command. The input bits to be compared are defined by this register. The convention of this mask register is opposite that of typical mask registers; bits that are 0 are used for matching while bits that 1 are used for masking. Typically, bits that are used for matching are the higher-order bits of the 64-bit CAM table entries, while the output bits are the lower-order bits. The mode of data entry is the next start-up function. The buffered-entry mode utilizes the entry queue while fast-entry mode bypasses the entry queue and enters data directly into the CAM table. If the fast-entry mode is used, the INITIALIZE TABLE command must be executed before matching operations can begin. In a typical application, the fast-entry mode is used at start-up to load initial data into the CAM table, followed by the INITIALIZE TABLE command. Then, the buffered-entry mode is used for normal operation. After the start-up functions are completed, the CAM table can be loaded. Each 64-bit data entry is constructed by writing a 16-bit value into each of the four I/O registers and issuing the INSERT VALUE command. After the INITIALIZE TABLE command is executed (if required), normal matching can begin. The DELETE VALUE command can be used to remove data from the CAM table. The flag register gives the status of various states of operation. If an error occurs, one of several error codes appears in the error code register. Although in this document the CAM interrupt (IRQ) signal is not used, several conditions can be programmed into the interrupt register to assert the CAM IRQ signal.
