Description
AVSS0
Input
Analog ground pin. This is used as the analog ground for the
respective modules. Supply this pin with the same voltage as the
VSS pin.
VREFH0
Input
Analog reference voltage supply pin for the ADC12 (unit 0). Connect
this pin to AVCC0 when not using the ADC12 (unit 0).
VREFL0
Input
Analog reference ground pin for the ADC12. Connect this pin to
AVSS0 when not using the ADC12 (unit 0).
VREFH
Input
Analog reference voltage supply pin for the ADC12 (unit 1) and D/A
Converter. Connect this pin to AVCC0 when not using the ADC12
(unit 1) and D/A Converter.
VREFL
Input
Analog reference ground pin for the ADC12 and D/A Converter.
Connect this pin to AVSS0 when not using the ADC12 (unit 1) and
D/A Converter.
ADC12
