Connect the AVSS0 pin to AVSS1 or AVSS2 when 12-bit A/D converter
unit 0 is not used.
Analog power supply and reference power supply pin for 12-bit A/D
converter unit 1. Connect the AVCC1 pin to AVCC0, AVCC2, or VREF
when 12-bit A/D converter unit 1 is not used.
Analog ground and reference ground pin for 12-bit A/D converter unit 1.
Connect the AVSS1 pin to AVSS0 or AVSS2 when 12-bit A/D converter
unit 1 is not used.
Analog power supply and reference power supply pin for 12-bit A/D
converter unit 2. Connect the AVCC2 pin to AVCC0, AVCC1, or VREF
when 12-bit A/D converter unit 2 is not used.
Analog ground and reference ground pin for 12-bit A/D converter unit 2.
Analog ground pin for comparator C and 8-bit D/A converter. Connect the
AVSS2 pin to AVSS0 or AVSS1 when 12-bit A/D converter unit 2,
comparator C and 8-bit D/A converter are not used.
Analog power supply pin for comparator C and 8-bit D/A converter. For the
64-pin LFQFP package, the VREF pin is internally connected to AVCC2
and is shared. Connect the VREF pin to AVCC0, AVCC1, or AVCC2 when
comparator C and 8-bit D/A converter are not used.
