(2) Scan mode start after single mode execution

In this special operation mode, scan operation is started subsequently after executing single mode

conversion (A/D conversion or comparate).

To start this mode in software, choose a software trigger using the A/D Scan Mode Register 0 A/D

conversion start trigger select bit. Then set the said register’s A/D conversion start bit to "1" during

single mode conversion operation.

To start this mode in hardware, choose a hardware trigger using the A/D Scan Mode Register 0 A/D

conversion start trigger select bit. Then enter the hardware trigger selected with the said register

during single mode conversion operation.

If a hardware trigger is selected using the A/D conversion start trigger select bit in both A/D Single

Mode Register 0 and A/D Scan Mode Register 0 and the selected hardware triggers are entered, the

A/D Converter first performs single mode conversion and then scan mode conversion in succession.

An A/D conversion interrupt or DMA transfer request can be generated when single mode conversion

on a specified channel or one cycle of scan operation is completed.
