is performed on the ADM during an A/D conversion operation, the conversion operation is initialized, and if the CS bit is
set (1), conversion will be started from the beginning.
A/D Converter
Operation
A/D conversion operations are performed successively until the CS bit is cleared (0) by software. If a write operation
