Description

Power supply

VCC, VSS

I Apply 2.7 to 5.5 V to VCC pin and 0 V to VSS pin.

Analog power

supply

Reset input

AVCC,

AVSS

RESET

Power supply for the A/D converter. Pins AVCC and AVSS should be

connected to VCC and VSS, respectively.

I Driving this pin low resets the MCU.

CNVSS

Main clock input

CNVSS

XIN

Main clock output XOUT

I Connect to VSS via a resistor.

I Input/output for the main clock oscillator. Connect a ceramic

resonator or crystal oscillator between XIN and XOUT. (1) To apply

O an external clock, connect it to XIN and leave XOUT open. When

XIN is not used, connect XIN to VCC pin and leave XOUT open.

Sub clock input

Sub clock output

XCIN

XCOUT

I Input/output for the sub clock oscillator. Connect a crystal oscillator

O between XCIN and XCOUT. (1)

Clock output
