145 / 180 page  TMP93CS32 2004-02-10 93CS32-143 The watchdog timer consists of 7-stage and 15-stage binary counters which use System clock (fSYS) as the input clock. The 15-stage binary counter has fSYS/215, fSYS/217, fSYS/219, and fSYS/221 output. Selecting one of the outputs with the WDMOD<WDTP1:0> register generates a watchdog interrupt when an overflow occurs. The binary counter for the watchdog timer should be cleared to “0” with runaway detecting result software (instruction) before an interrupt occurs. Example: LDW (WDMOD), B100H ; Disable. LD (WDCR), 4EH ; Write clear code. SET 7, (WDMOD) ; Enable again. The runaway detecting result can also be connected to the reset pin internally. In this case, the watchdog timer resets itself. Figure 3.11.2 Normal Mode Figure 3.11.3 Reset Mode For warm-up counter, 27 and 29 output of 15-stage binary counter can be selected using WDMOD<WARM> register. When a stable-external oscillator is used, shorter warm-up time is available using T45CR<QCU> register. When <QCU> = 1, counting value 27 is selected. When the watchdog timer is in operation, this shorter warm-up time function cannot be available. This function can be available by setting <QCU> = 0. Overflow n 0 WDT counter WDT interrupt WDT clear (Soft ware) Write clear code n WDT counter WDT interrupt 8 to 20 states (12.8 to 32 µs at 20 MHz) Overflow Internal reset |
