Note: *0: Low level input
1: High level input
Reset input
Input a low level pulse with a length of at least 4 clock cycles to reset
and restart IC operation. Note that when a 4 MHz oscillator is used,
since a single clock cycle is 0.25µs, four clock cycles is 1 µs.
Schmitt type input.
Built-in pull-up resistor
