3.5 A/D Channel Multiplexer Register
The A/D channel multiplexer register is used to select the A/D channel
under normal mode, or the stop channel number under the auto-scan
mode. Refer to section 3.7 to find the definition of the auto-scan control
bit ‘ASCAN’. When auto scanning is disabled, the register values select
the AD channel number.
When auto scanning is enabled, the register values set the stop channel
number while the starting channel is from channel 0. After every A/D
conversion, the A/D channel to be selected will be increased by one
automatically until the channel number reach this register value, then
channel 0 is selected again.

CS3 ... CS0: Stop multiplexer channel number.
Note that as the hardware jumpers set the ACL-8316/12 to differential
input mode, only 8 channels are available. The CS3 value is useless. The
initial value of the channel number is 0.
