Reset input

Clock input

Clock output

I Connect to VCC when VCC = 4.5 V to 5.5 V.

Connect to Vpp (=4.5 V to 5.5 V) when VCC = 2.7 V to 4.5 V.

I Reset input pin. While reset is “L” level, a 20 cycle or longer clock

must be input to XIN pin.

I Connect a ceramic resonator or crystal oscillator between XIN and

XOUT pins. To input an externally generated clock, input it to XIN pin

O and open XOUT pin.
