(1) Power-on reset
Reset can be automatically performed at power on (power-on re-
set) by the built-in power-on reset circuit. When the built-in
power-on reset circuit is used, the time for the supply voltage to
rise from 0 V until the value of supply voltage reaches the minimum
operating voltage must be set to 100
s or less.
If the rising time exceeds 100
s, connect a capacitor between the
RESET pin and VSS at the shortest distance, and input “L” level to
RESET pin until the value of supply voltage reaches the minimum
operating voltage.

Notes 1:
This symbol represents a parasitic diode.
2: Applied potential to RESET pin must be VDD or less.
3: Keep the value of supply voltage to the minimum value
or more of the recommended operating conditions.
