Analog power supply

AVCC0

Input

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

Connect this pin to a branch from the VCC power supply.

Connect the pin to AVSS0 via a 0.1-µF multilayer ceramic

capacitor. The capacitor should be placed close to the pin.

Input

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

(unit 0). Connect this pin to VCC if the 12-bit A/D converter is

not to be used.

VREFL0

Input

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

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

be used.
