1. Overview

Note:

When not using any of the A/D converter, D/A converter, comparator C and temperature sensor, connect the AVCC0, AVCC1

and AVCC2 pins to VCC, and connect the AVSS0, AVSS1 and AVSS2 pins to VSS, respectively.

Note 1. This pin functions as MD after release from the reset state, and the pull-up resistor connected to the MD pin is enabled.

Note 2. This pin functions as EMLE after release from the reset state, and the pull-down resistor connected to the EMLE pin is enabled.

Analog power supply

AVCC0

Input

Analog voltage supply pin for 12-bit A/D converter unit 0.

Connect the AVCC0 pin to AVCC1 or AVCC2 when 12-bit A/D

converter unit 0 is not used.

AVSS0

Input

Analog ground pin for 12-bit A/D converter unit 0. Connect the

AVSS0 pin to AVSS1 or AVSS2 when 12-bit A/D converter unit

0 is not used.

AVCC1

Input

Analog voltage supply pin for 12-bit A/D converter unit 1.

Connect this pin to AVCC0 when not using the 12-bit A/D

converter 1 but using the 12-bit A/D converter 0.

Connect this pin to AVCC2 when not using the 12-bit A/D

converter 0 and the 12-bit A/D converter 1.

AVSS1

Input

Analog ground pin for 12-bit A/D converter unit 1.

Connect this pin to AVSS0 when not using the 12-bit A/D

converter 1 but using the 12-bit A/D converter 0.

Connect this pin to AVSS2 when not using the 12-bit A/D

converter 0 and the 12-bit A/D converter 1.

AVCC2

Input

Analog voltage supply pin for the 12-bit A/D converter unit 2,

reference voltage supply pin for the 12-bit D/A converter, analog

voltage supply pin for the comparator C, and analog voltage

supply pin for the temperature sensor.

Connect this pin to either of AVCC0 or AVCC1 when not using

the 12-bit A/D converter unit 2, 12-bit D/A converter, comparator

C, and temperature sensor.

AVSS2

Input

Analog ground pin for the 12-bit A/D converter unit 2, reference

ground pin for the D/A converter, analog ground pin for the

comparator C, and analog ground pin for the temperature

sensor.

Connect this pin to either of AVSS0 or AVSS1 when not using

the 12-bit A/D converter unit 2, 12-bit D/A converter, comparator

C, and temperature sensor.
