Function
Input from main CPU to watchdog timer 1 (WDT1)
For connecting capacitor Cf1 to determine WDT1 filter characteristic (frequency band)
For connecting common bias resistor Rf to determine WDT1 and WDT2 filter
characteristics (frequency band), power-on reset time (t
, common to
RES1
and
RES2
), clock-off time of auto-reset circuits 1 and 2, reset high time (t
and t
),reset
low time (t
and t
), and reset pulse delay at voltage drop and recovery. Use the
resistor value from 100 k
to 500 k
.
For connecting capacitor C

For adjusting standby trigger voltage (insert a resistor between this pin and ground)
Recommended range: V
