AVREF

—

—

A/D converter reference voltage

AVSS

—

A/D converter reference GND potential

X1

I

—

Crystal/ceramic connection pin for the main system

X2

—

clock oscillator. When inputting the external clock,

input the external clock to pin X1, and the inverted

phase of the external clock to pin X2.

XT1

I

—

Crystal connection pin for the subsystem clock

XT2

—

oscillator. When the external clock is used, input the

external clock to pin XT1, and the inverted phase of

the external clock to pin XT2. Pin XT1 can be used

as a 1-bit input (test) pin.

RESET

I

—

System reset input (low-level active)

Note Circuit types enclosed in brackets indicate Schmitt triggered inputs.
