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 ANmn Input Input pins for the analog signals to be processed by the A/D converter. (m: ADC unit number, n: pin number) ADTRGm Input Input pins for the external trigger signals that start the A/D conversion, active-low. DAC12 DAn Output Output pins for the analog signals processed by the D/A converter. CTSU TSn Input Capacitive touch detection pins (touch pins) TSCAP I/O Secondary power supply pin for the touch driver I/O ports Pmn I/O General-purpose input/output pins (m: port number, n: pin number) P200 Input General-purpose input pin RA4M2 Datasheet 1.
