Description
Setting bits in the A/D analog input channel select
register to 1 selects a channel that corresponds to a
specified bit. For the correspondence between analog
input pins and bits, see table 17.3.
When changing the analog input channel, the ADST bit in
ADCR must be cleared to 0 to prevent incorrect
operations.
