PWM output 0
PWM output 1
Data input (IEBus)
Data output (IEBus)
Capacitance connection for stabilizing the regulator output/power supply
when the regulator is stopped. Connect to VSS via a capacitor of order of 1µF.
Signal for specifying regulator operation
Chip reset
Crystal input for system clock oscillation (A clock pulse can also be input
to the X1 pin.)
Watch clock connection
Analog voltage input for A/D converter
To apply the reference voltage for A/D converter
Positive power supply for A/D converter
GND for A/D converter
Positive power supply
GND
Connect directly to VSS. (This pin is for IC test.)
