Section 19 A/D Converter
19.2.2
ADCSR is an 8-bit readable/writable register that controls A/D conversion operations.
ADCSR is initialized to H'00 by a reset, and in standby mode, watch mode, subactive mode,
subsleep mode, and module stop mode.
Bit 7—A/D End Flag (ADF): Status flag that indicates the end of A/D conversion.
