Input

FDP voltage supply when incorporated pull-down (PD) resistor is set by

mask option.

Crystal connectors for system clock oscillation. When the clock is

supplied externally, input to EXTAL; opposite phase clock should be

input to XTAL.

Low-level active, system reset.

NC. Under normal operation, leave this pin open.

VCC supply.

GND.

FDP segment signal (anode

connection) outputs.

(8 pins)

Crystal connectors for 32kHz timer/counter clock

oscillation. For usage as event counter, input to TEX,

and leave TX open.

(Port G)

8-bit output port.

(8 pins)

FDP segment signal (anode

connection) outputs.
