c513ao data sheet 23 02.00 parallel i/o port the c513ao has four 8-bit i/o ports. port 0 is an open-drain bidirectional i/o port, while ports 1, 2, and 3 are quasi-bidirectional i/o ports with internal pull-up resistors. thus, when configured as inputs, ports 1 to 3 will be pulled high and will source current when externally pulled low. port 0 will float when configured as input. the output drivers of port 0 and port 2 and the input buffers of port 0 are also used for accessing external memory. in this application, port 0 outputs the low byte of the external memory address, time multiplexed with the byte being written or read. port 2 outputs the high byte of the external memory address when the address is 16 bits wide. otherwise, the port 2 pins continue to emit the p2 sfr contents. in this case, port 0 is not an open-drain port, but uses a strong internal pull-up field effect transistors (fets). port 1 pins used for synchronous serial channel (ssc) outputs are true push-pull outputs. when used as ssc inputs, they float (no pull-up). c513ao_ds_0200.frm page 23 wednesday, august 30, 2000 12:45 pm

c513ao data sheet 26 02.00 serial interface (usart) the serial port is a full duplex port capable of simultaneous transmit and receive functions. it is also receive-buffered; it can commence reception of a second byte before a previously-received byte has been read from the receive register. the serial port can operate in 4 modes (one synchronous and three asynchronous) as illustrated in table 6 . for clarification, some terms regarding the difference between baudrate clock and baudrate should be mentioned. the serial interface requires a clock rate which is 16 times the baudrate for internal synchronization. therefore, the baudrate generators must provide a baudrate clock to the serial interface which divides it by 16, thereby resulting in the actual baudrate. the baudrates in mode 1 and 3 are determined by the timer overflow rate. these baudrates can be determined by timer 1 or by timer 2 or both (one for transmit, the other for receive). table 6 usart operating modes mode scon description sm0 sm1 0 0 0 shift register mode serial data enters and exits through r d. t d outputs the shift clock. 8-bit data are transmitted/received (lsb first) at a fixed baudrate of 1 / 12 th of the oscillator frequency. 1 0 1 8-bit usart, variable baudrate 10 bits are transmitted (through t d) or received (at r d). 2 1 0 9-bit usart, fixed baudrate 11 bits are transmitted (through t d) or received (at r d). 3 1 1 9-bit usart, variable baudrate similar to mode 2, except for the variable baudrate. c513ao_ds_0200.frm page 26 wednesday, august 30, 2000 12:45 pm

c513ao data sheet 28 02.00 ssc interface the synchronous serial channel (ssc) interface is compatible to the popular spi serial bus interface. it can be used for simple i/o expansion via shift registers, for connection with a variety of peripheral components (such as a/d converters, eeproms etc.), or interconnection of several microcontrollers in a master/slave structure. the ssc unit supports full-duplex or half-duplex operation and can run in master mode or slave mode. figure 15 shows the block diagram of the ssc. figure 15 ssc block diagram interrupt system the c513ao provides seven interrupt sources with two priority levels. five of the interrupts can be generated by the on-chip peripherals (timer 0, timer 1, timer 2, usart, and ssc) and three of the interrupts may be triggered externally (p1.1/t2ex, p3.2/int0, p3.3/int1). a non-maskable eighth interrupt is reserved for external wake-up from power-down mode. figure 16 gives a general overview of the interrupt sources and illustrates the request and the control flags. table 8 lists the vector addresses of each interrupt source. mcb02735 p1.2/sclk p1.3/sri p1.4/sto p1.5/sls pin control logic shift register receive buffer register stb clock selection clock divider srb f osc control register status register int. enable reg. scien ssccon scf control logic internal bus interrupt c513ao_ds_0200.frm page 28 wednesday, august 30, 2000 12:45 pm

c513ao data sheet 31 02.00 fail save mechanisms the c513ao offers enhanced fail-safe mechanisms which allow automatic recovery from a software upset or a hardware failure: ? a programmable watchdog timer (wdt) has variable time-out period from 512 m s up to approx. 1.1 sec. at 12 mhz ? an oscillator watchdog (owd) monitors the on-chip oscillator and forces the microcontroller into reset state if the on-chip oscillator fails. it also provides the clock for a fast internal reset after power-on. the watchdog timer in the c513ao is a 15-bit timer which is incremented by a count rate of either f cycle /2 or f cycle /32 ( f cycle = f osc /12). that is, the machine clock is divided by a fixed divide-by-two prescaler and an optional divide-by-16 prescaler arranged in series. for programming of the watchdog timer overflow rate, the upper 7 bit of the watchdog timer can be written. figure 17 shows the block diagram of the watchdog timer unit. figure 17 block diagram of the watchdog timer the watchdog timer can be started by software (bit swdt in sfr wdcon); but, it cannot be stopped during active mode of the device. if the software fails to clear the watchdog timer, an internal reset will be initiated. the reset cause can be examined by software (status flag wdts in wdcon is set). a refresh of the watchdog timer is done by setting bits wdt (sfr wdcon) and swdt consecutively. this double instruction sequence has been implemented to increase system security. during a refresh, the content of the sfr wdtrel is transferred to sfr wdth, i.e. the upper 7-bit of the watchdog timer. it must be noted, however, that the watchdog timer is stopped during the idle mode and power down mode of the processor. c513ao_ds_0200.frm page 31 wednesday, august 30, 2000 12:45 pm
c513ao data sheet 32 02.00 oscillator watchdog the oscillator watchdog (owd) unit is used for three functions: ? monitoring the on-chip oscillators function the watchdog supervises the on-chip oscillators frequency. if the frequency is lower than the frequency of the auxiliary rc oscillator in the watchdog unit, the internal clock is supplied by the rc oscillator and the device is brought into reset. if the failure condition disappears (that is, if the on-chip oscillator has a higher frequency than the rc oscillator), the device executes a final reset phase of typically 1 ms to allow the oscillator to stabilize. then, the oscillator watchdog reset is released and the device resumes program execution. ? fast internal reset after power-on the oscillator watchdog unit provides a clock supply for reset before the on-chip oscillator has started. the oscillator watchdog unit reset works identically to the monitoring function. ? control of external wake-up from software power-down mode when power-down mode is terminated by a low level at the int0 pin, the oscillator watchdog unit ensures that the microcontroller resumes operation (execution of the power-down wake-up interrupt) with the nominal clock rate. in power-down mode, the rc oscillator and the on-chip oscillator are stopped. both oscillators are started again when power-down mode is terminated. when the on-chip oscillator has a frequency higher than the rc oscillator, the microcontroller starts operation after a final delay of typ. 1 ms to allow the on-chip oscillator to stabilize. note: the oscillator watchdog unit is always enabled. figure 18 shows the block diagram of the oscillator watchdog unit. c513ao_ds_0200.frm page 32 wednesday, august 30, 2000 12:45 pm

c513ao data sheet 34 02.00 power saving modes the c513ao provides three basic power-saving modes: idle mode, slow-down mode, and power- down mode. ? idle mode the cpu is gated off from the oscillator. all peripherals are still provided with the clock and are able to function. idle mode is entered by software and can be left by an interrupt or reset. ? slow down mode the controller keeps up the full operating functionality, but its normal clock frequency is internally divided by 32. this slows down all parts of the controller, the cpu and all peripherals, to 1/32nd of their normal operating frequency and also reduces power consumption. ? power down mode the operation of the c513ao is completely stopped and the oscillator is turned off. this mode is used to save the contents of the internal ram with a very low standby current. this power down mode is entered by software and can be left by reset or a short low pulse at pin p3.2/int0 . in the power down mode of operation, v dd can be reduced to minimize power consumption. it must be ensured, however, that v dd is not reduced before the power down mode is invoked, and that v dd is restored to its normal operating level, before the power down mode is terminated. table 10 gives a general overview of the entry and exit procedures of the power saving modes. table 10 power saving modes overview mode entering example leaving by remarks idle mode orl pcon, #01 h occurrence of an any enabled interrupt cpu clock is stopped; cpu maintains their data; peripheral units are active (if enabled) and provided with clock hardware reset slow down mode in normal mode: orl pcon,#10 h anl pcon,#0ef h or hardware reset internal clock rate is reduced to 1/32 of its nominal frequency with idle mode: orl pcon,#11 h occurrence of any enabled interrupt and the instruction anl pcon,#0ef h cpu clock is stopped; cpu maintains their data; peripheral units are active (if enabled) and provided with 1/32 of its nominal frequency hardware reset power down mode orl pcon, #02 h hardware reset oscillator is stopped; contents of on-chip ram and sfrs are maintained; short low pulse at pin p3.2/int0 c513ao_ds_0200.frm page 34 wednesday, august 30, 2000 12:45 pm

c513ao data sheet 38 02.00 notes: 1) capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the v ol of ale and port 3. the noise is due to external bus capacitance discharging into the port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operation. in the worst case (capacitive loading > 100 pf), the noise pulse on ale line may exceed 0.8 v. in such cases it may be desirable to qualify ale with a schmitt-trigger, or use an address latch with a schmitt-trigger strobe input. 2) capacitive loading on ports 0 and 2 may cause the v oh on ale and psen to momentarily fall below the 0.9 v dd specification when the address lines are stabilizing. 3) i pd (power-down mode) is measured under following conditions: ea =port0= v dd ; reset = v ss ; xtal2 = n.c.; xtal1 = v ss ; all other pins are disconnected. i dd would be slightly higher if a crystal oscillator is used (appr. 1 ma). 4) i dd (active mode) is measured with: xtal2 driven with t clch , t chcl =5ns, v il = v ss +0.5v, v ih = v dd C 0.5 v; xtal1 = n.c.; ea = pe /swd = port 0 = port 6 = v dd ; hwpd = v dd ; reset = v dd ; all other pins are disconnected. i dd would be slightly higher if a crystal oscillator is used (appr. 1 ma). 5) i dd (idle mode) is measured with all output pins disconnected and with all peripherals disabled; xtal1 driven with t clch , t chcl =5ns, v il = v ss +0.5v, v ih = v dd C 0.5 v; xtal2 = n.c.; reset = ea = v ss ; port0 = v dd ; all other pins are disconnected. 6) i dd (active mode with slow-down mode) is measured with all output pins disconnected and with all peripherals disabled; xtal1 driven with t clch , t chcl =5ns, v il = v ss +0.5v, v ih = v dd C 0.5 v; xtal2 = n.c.; reset = ea = v ss ;port0= v dd ; all other pins are disconnected. 7) i dd (idle mode with slow-down mode) is measured with all output pins disconnected and with all peripherals disabled; xtal1 driven with t clch , t chcl =5ns, v il = v ss +0.5v, v ih = v dd C 0.5 v; xtal2 = n.c.; reset = ea = v ss ;port0= v dd ; all other pins are disconnected. 8) overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified range (i.e. v ov > v dd +0.5v or v ov < v ss C 0.5 v). the supply voltage v dd and v ss must remain within the specified limits. the absolute sum of input currents on all port pins may not exceed 50 ma. 9) not 100% tested, guaranteed by design characterization. 10)the typical i dd values are periodically measured at t a = + 25 c and v dd = 5 v but not 100% tested. c513ao_ds_0200.frm page 38 wednesday, august 30, 2000 12:45 pm
