3 ADCSEL 0: Software trigger R W
A-D conversion start trigger select bit 1: Hardware trigger
4 ADCREQ 0: A-D conversion interrupt request R W
Interrupt/DMA transfer request select bit 1: DMA transfer request
5 ADCCMP 0: A-D conversion in progress R –
A-D conversion completed bit 1: A-D conversion completed
6 ADCSTP 0: No operation 0 W
A-D conversion stop bit 1: Stop A-D conversion

Note 1: Two bits—A-D hardware trigger select 1 (bit 0) and A-D hardware trigger select 0 (bit 2)—are used to select an A-D
hardware trigger.
A-D Scan Mode Registers 0 are used to control operation of the A-D Converters during scan mode.
(1) ADCTRG (A-D Hardware Trigger Select) bits (Bits 0 and 2)
These bits select a hardware trigger when A-D conversion by the A-D Converter is to be started in hardware.
Select one from the following hardware trigger sources:
A-D0 Converter: Input event bus 2 A-D1 Converter: Input event bus 2
Input event bus 3 Input event bus 3
Output event bus 3 TID1 underflow/overflow
TIN23 edge select output TIN23 edge select output
The contents of these bits are ignored if a software trigger is selected by ADCSEL (A-D conversion start
trigger select bit).
