Bit 3—Clock Select (CKS): Sets the A/D conversion time. Only change the conversion time
while ADST = 0.
Bits 2 to 0—Channel Select 2 to 0 (CH2 to CH0): Together with the SCAN bit, these bits select
the analog input channel(s).
One analog input channel can be switched to digital input.
Only set the input channel while conversion is stopped.
