Must write 0.
CS0 Digital Comparator Polarity Select.
0: The digital comparator generates an interrupt if the conversion is greater than
the threshold.
1: The digital comparator generates an interrupt if the conversion is less than or
equal to the threshold.
CS0 Double Reset Select.
These bits adjust the secondary CS0 reset time. For most touch-sensitive
switches, the default (fastest) value is sufficient. See the discussion in Section
8.13 for more information.
00: No additional time is used for secondary reset.
01: An additional 0.75 µs is used for secondary reset.
10: An additional 1.5 µs is used for secondary reset.
11: An additional 2.25 µs is used for secondary reset.
CS0 Wake on Interrupt Configuration.
0: Wake-up event generated on digital comparator interrupt only.
1: Wake-up event generated on end of scan or digital comparator interrupt.
CS0 Capacitance Gain Select.
These bits select the gain applied to the capacitance measurement. Lower gain
values increase the size of the capacitance that can be measured with the CS0
module. The capacitance gain is equivalent to CS0CG[2:0] + 1.
000: Gain = 1x
