Bits 1 and 0—Channel Select 1 and 0 (CH1 and CH0): These bits, together with the SCAN bit,
select the analog input channels.
To prevent incorrect operation, ensure that the ADST bit in A/D control/status register 1
(ADCSR1) is cleared to 0 before changing the analog input channel selection.
14.2.5
A/D control register 1 (ADCR1) is an 8-bit readable/writable register that controls the start of A/D
conversion and selects the operating clock.
ADCR1 is initialized to H'7F by a power-on reset, and in hardware standby mode and software
standby mode.
Bit 7—Trigger Enable (TRGE): Same as TRGE in ADCR0.
Bits 6 to 0—Reserved: These bits are always read as 1, and should only be written with 1.
