CS0 Channel Scan Masking Enable.
0: The CS0SCAN0 and CS0SCAN1 register contents are ignored.
1: The CS0SCAN0 and CS0SCAN1 registers are used to determine which
channels will be included in the scan.
CS0 Start of Conversion Mode Select.
000: Conversion initiated on every write of 1 to CS0BUSY.
001: Conversion initiated on overflow of Timer 0.
010: Conversion initiated on overflow of Timer 2.
011: Conversion initiated on overflow of Timer 1.
100: Conversion initiated on overflow of Timer 3.
When CS0SMEN = 0
101: Reserved.
110: Conversion initiated continuously on the channel selected by CS0MX after
writing 1 to CS0BUSY.
111: Conversions initiated continuously on channels from CS0SS to CS0SE after
writing 1 to CS0BUSY.
When CS0SMEN = 1
101: Single Scan Mode, scans the channels selected by CS0SCAN0/1 once.
110: Conversion initiated continuously on the channel selected by CS0MX after
writing 1 to CS0BUSY.
111: Auto Scan Mode, continuously scans the channels selected by
CS0SCAN0/1.
CS0 Multiple Channel Enable.
0: Multiple channel feature is disabled.
1: Channels selected by CS0SCAN0/1 are internally shorted together and the
combined node is selected as the CS0 input. This mode can be used to detect a
capacitance change on multiple channels using a single conversion.
