Notes on Watchdog Timer
(1) The watchdog timer operates in wait mode. To prevent
underflow, write to the watchdog timer control register.
The watchdog timer stops in stop mode, but starts counting
at the same time as exiting stop mode. After exiting stop
mode, it continues counting during oscillation stabilization
time. To prevent underflow during the period, the watchdog
timer H count source selection bit (bit 7) in the watchdog
timer control register (address 0039
16
) should be set to “0”
before executing the STP instruction.
Note that the watchdog timer continues counting even if the
STP instruction is executed in the following two conditions:
1
Stopping the low-speed on-chip oscillator: Disabled (bit
4 in FSROM2)
Source clock of the watchdog timer: Low-speed on-chip
oscillator/16 (bit 0 in FSROM2)
2
Stopping the low-speed on-chip oscillator: Disabled (bit
4 in FSROM2)
Source clock of the watchdog timer:
φ
SOURCE (bit 0 in
FSROM2)
φ
SOURCE: Low-speed on-chip oscillator (bits 5 and 4 in
CLKM)
(2) STP instruction function selection bit
The function of the STP instruction can be selected by the bit
2 in FSROM2. This bit cannot be used for rewriting by
executing the STP instruction.
When this bit is set to “0”, stop mode is entered by
executing the STP instruction.
When this bit is set to “1”, internal reset occurs by
executing the STP instruction.
