Description

VCC,VSS

Apply program/erase protection voltage to Vcc pin and 0 V to Vss pin.

CNVSS

Connect to Vcc pin.

RESET

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

must be input to XIN pin.

XIN

Connect a ceramic resonator or crystal oscillator between XIN and

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

and open XOUT pin.

XOUT

BYTE

Connect this pin to VSS or VCC.

AVCC, AVSS

VREF

Connect AVSS to VSS and AVCC to VCC, respectively.

Enter the reference voltage for AD from this pin.
