RX630 Group 1. Overview
12-bit A/D converter AN000 to AN020 Input Input pins for the analog signals to be processed by the A/D
converter
ADTRG0# Input Input pins for the external trigger signals that start the A/D
conversion
10-bit A/D converter AN0 to AN7 Input Input pins for the analog signals to be processed by the A/D
converter
ANEX0 Output Extended analog output pin
ANEX1 Input Extended analog input pin
ADTRG# Input Input pins for the external trigger signals that start the A/D
conversion
D/A converter DA0, DA1 Output Output pins for the analog signals to be processed by the D/A
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
