converter.

Analog power supply

AVCC0

Input

Analog voltage supply pin for the 12-bit A/D converter. Connect

this pin to VCC if the 12-bit A/D converter is not to be used.

AVSS0

Input

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

to VSS if the 12-bit A/D converter is not to be used.

VREFH0

Input

Analog reference voltage supply pin for the 12-bit A/D converter.

Connect this pin to VCC if the 12-bit A/D converter is not to be

used.

Analog power supply

VREFL0

Input

Analog reference ground pin for the 12-bit A/D converter.

Connect this pin to VSS if the 12-bit A/D converter is not to be

used.

VREFH

Input

Reference voltage input pin for the 10-bit A/D converter and D/A

converter. This is used as the analog power supply for the

respective modules. Connect this pin to VCC if neither the 10-bit

A/D converter nor the D/A converter is in use.

VREFL

Input

Reference ground pin for the 10-bit A/D converter and D/A

converter. This is used as the analog ground for the respective

modules. Set this pin to the same potential as the VSS pin.
