Section 14 A/D Converter
14.2.2
ADCSR is an 8-bit readable/writable register that controls A/D conversion operations and shows
the status of the operation.
ADCSR is initialized to H'00 by a reset, and in hardware standby mode or module stop mode.
Bit 7—A/D End Flag (ADF): Status flag that indicates the end of A/D conversion.
