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.
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.
