This register selects the channels for the auto-mode sequence. The device scans only the selected channels in
ascending order during auto-scan mode, starting with the lowest channel selected. For example, if the Auto-Md
Ch-Sel register is programmed to 01100100, then the auto-mode sequence is channels 2, 5, 6, 2, 5, 6…2, 5, 6.
In this case, the sequence always starts at channel 2. Channel 0 is selected if this register is programmed to
00000000.
