15. AC PIN (ALL CLEAR PIN)
Internal part of the CPU including the program counter can be reset by setting the AC pin to the low level.
Watchdog Timer Function
A power-on reset function and a CR watchdog timer function, that can be controlled by program, can be realized
by connecting a 0.1
μ
F capacitor across the AC pin and the V

pattern
Discharge start instruction
Discharge starts after the NOP
instruction execution.
(Discharge time is about 5 ms from V to V )
The pattern must be
controlled by the program,
in such a manner that
the C charge level will not
go below V .

Caution
When the watchdog timer function is not used, switch to charging mode by executing a NOP
instruction immediately before a HALT instruction at the beginning of the program. (Be sure
to connect the capacitor.)
