(2) Scan mode start after single mode execution
In this special operation mode, scan operation is started subsequently after executing single mode conver-
sion (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 conver-
sion 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 conver-
sion 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.
