21 / 176 page  R01DS0331EJ0100 Rev.1.00 Page 21 of 176 Feb 08, 2019 RX72T Group 1. Overview 12-bit A/D converter AN000 to AN002, AN100 to AN102 Input Input pins for the analog signals to be processed by the A/D converter. (Positive side input at PGA pseudo-differential input.) AN003 to AN007, AN103 to AN107, AN200 to AN211, AN216 to AN217 Input Input pins for the analog signals to be processed by the A/D converter. ADST0, ADST1, ADST2 Output Output pins for A/D conversion status. ADTRG0#, ADTRG1#, ADTRG2# Input Input pins for the external trigger signals that start the A/D conversion. PGAVSS0, PGAVSS1 Input A common reference ground pin for PGA pseudo-differential input in the unit 12-bit D/A converter DA0, DA1 Output Output pins for the analog signals to be processed by the D/A converter Comparator C COMP0 to COMP5 Output Comparator detection result output pins. CVREFC0, CVREFC1 Input Analog reference voltage supply pins for comparator C. CMPCnm Input Analog input pin for CMPCnm (n = 0 to 5, m = 0 to 3) Analog power supply AVCC0 — Analog voltage supply pin for 12-bit A/D converter unit 0. Connect the AVCC0 pin to AVCC1 or AVCC2 when 12-bit A/D converter unit 0 is not used. AVSS0 — Analog ground pin for 12-bit A/D converter unit 0. Connect the AVSS0 pin to AVSS1 or AVSS2 when 12-bit A/D converter unit 0 is not used. AVCC1 — Analog voltage supply pin for 12-bit A/D converter unit 1. Connect this pin to AVCC0 when not using the 12-bit A/D converter 1 but using the 12-bit A/D converter 0. Connect this pin to AVCC2 when not using the 12-bit A/D converter 0 and the 12-bit A/D converter 1. AVSS1 — Analog ground pin for 12-bit A/D converter unit 1. Connect this pin to AVSS0 when not using the 12-bit A/D converter 1 but using the 12-bit A/D converter 0. Connect this pin to AVSS2 when not using the 12-bit A/D converter 0 and the 12-bit A/D converter 1. AVCC2 — Analog voltage supply pin for the 12-bit A/D converter unit 2, reference voltage supply pin for the 12-bit D/A converter, analog voltage supply pin for the comparator C, and analog voltage supply pin for the temperature sensor. Connect this pin to either of AVCC0 or AVCC1 when not using the 12-bit A/D converter unit 2, 12-bit D/A converter, comparator C, and temperature sensor. AVSS2 — Analog ground pin for the 12-bit A/D converter unit 2, reference ground pin for the D/A converter, analog ground pin for the comparator C, and analog ground pin for the temperature sensor. Connect this pin to either of AVSS0 or AVSS1 when not using the 12-bit A/D converter unit 2, 12-bit D/A converter, comparator C, and temperature sensor.
