C.6 MUX Scan Channel Control — BASE+02H
The write register at BASE+02H controls multiplexer (MUX) scanning.
The high nibble provides the stop scan channel number, and the low nib-

trigger sets the MUX to the next channel.
With continuous triggering the MUX will scan from the start channel to
the end channel, then repeat. For example, if the start channel is 3 and the
stop channel is 7, then the scan sequence is 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 3,
