RX63N Group, RX631 Group 1. Overview
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.
