WATCHDOG TIMER
Watchdog timer provides a method to reset the system when a pro-
gram runs wild. Watchdog timer consists of a 16-bit timer (WDT),
watchdog timer enable flag (WEF), and watchdog timer flags
(WDF1, WDF2).
The timer WDT downcounts the instruction clocks as the count
source. The underflow signal is generated when the count value
reaches “0000
16
.” This underflow signal can be used as the timer 2
count source.
When the WRST instruction is executed after system is released
from reset, the WEF flag is set to “1”. At this time, the watchdog
timer starts operating.
When the count value of timer WDT reaches “BFFF
16
” or “3FFF
16
,”
the WDF1 flag is set to “1.” If the WRST instruction is never ex-
ecuted while timer WDT counts 32767, WDF2 flag is set to “1,” and
the RESET pin outputs “L” level to reset the microcomputer. Ex-
ecute the WRST instruction at each period of 32766 machine cycle
or less by software when using watchdog timer to keep the micro-
computer operating normally.
To prevent the WDT stopping in the event of misoperation, WEF
flag is designed not to initialize once the WRST instruction has
been executed. Note also that, if the WRST instruction is never ex-
ecuted, the watchdog timer does not start.
Fig. 20 Watchdog timer function
The contents of WEF, WDF1 and WDF2 flags and timer WDT are
initialized at the RAM back-up mode.
If WDF2 flag is set to “1” at the same time that the microcomputer
enters the RAM back-up state, system reset may be performed.
When using the watchdog timer and the RAM back-up mode, ini-
tialize the WDF1 flag with the WRST instruction just before the
microcomputer enters the RAM back-up state (refer to Figure 21)
