CS0 Double Reset Select.
These bits adjust the secondary CS0 reset time. For most touch-sensitive
switches, the default (fastest) value is sufficient, and these bits should not be
modified.
00: No additional time is used for secondary reset (recommended for most
switches)
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 Reference Gain Select.
These bits select the "gain" applied to the current used to charge an internal refer-
ence capacitor. Lower gain values decrease the current setting, and increase
both the size of the capacitance that can be measured with the CS0 module, and
the base conversion time. Refer to “15.2. CS0 Gain Adjustment” on page 81 for
more information.
