CS0 Conversion Rate.
These bits control the conversion rate of the CS0 module. See the electrical spec-
ifications table for specific timing.
00: Conversions last 12 internal CS0 clocks and are 12 bits in length.
01: Conversions last 13 internal CS0 clocks and are 13 bits in length.
10: Conversions last 14 internal CS0 clocks and are 14 bits in length.
11: Conversions last 16 internal CS0 clocks.and are 16 bits in length.
CS0 Discharge Time.
These bits adjust the primary CS0 reset time. For most touch-sensitive switches,
the default (fastest) value is sufficient. See the discussion in Section 8.13 for more
information.
000: Discharge time is 0.75 µs (recommended for most switches)
001: Discharge time is 1.0 µs
010: Discharge time is 1.2 µs
011: Discharge time is 1.5 µs
100: Discharge time is 2 µs
101: Discharge time is 3 µs
110: Discharge time is 6 µs
111: Discharge time is 12 µs
CS0 Output Current Adjustment.
These bits allow the user to adjust the output current used to charge up the capac-
itive sensor element. For most touch-sensitive switches, the default (highest) cur-
rent is sufficient. See the discussion in Section 8.13 for more information.
000: Full Current
001: 1/8 Current
010: 1/4 Current
011: 3/8 Current
100: 1/2 Current
101: 5/8 Current
