Input

FDP voltage supply when incorporated resistor is set by mask option.

T0 to T7

FDP timing signal outputs.

Crystal connectors for system clock oscillation. When the clock is

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

input to XTAL.

Crystal connectors for 32kHz timer/counter clock oscillation. Set 32kHz

crystal oscillator between TEX and TX. For usage as event input, attach

clock source to TEX, and open TX.

Low-level active, system reset.

NC. Under normal operation, connect to VDD.

AVDD

Positive power supply for A/D converter.

Reference voltage input for A/D converter.

A/D converter GND.

Positive power supply.

GND.
