A/D control/status register 0 (ADCSR0) is an 8-bit readable/writable register whose functions
include selection of the A/D conversion mode for A/D0.
ADCSR0 is initialized to H'00 by a power-on reset, and in hardware standby mode and software
standby mode.
Note:
Bit 7—A/D End Flag (ADF): Indicates the end of A/D conversion.
