respective modules. Supply this pin with the same voltage as the

VSS pin.

VREFH

Input

Analog reference voltage supply pin for the D/A Converter.

VREFL

Input

Analog reference ground pin for the D/A Converter.

VREFH0

Input

Analog reference voltage supply pin for the ADC12. Connect this pin

to AVCC0 when not using the ADC12.

VREFL0

Input
