0h = Enable wetting current reduction (to 2 mA) for 10mA and 15mA
settings upon TW event for all inputs enabled with CSI.
1h = Disable wetting current reduction (to 2 mA) for 10mA and 15mA
settings upon TW event for all inputs enabled with CSI.
For detailed descriptions for the detection filter, refer to section
Detection Filter.
0h = every sample is valid and taken for threshold evaluation
1h = 2 consecutive and equal samples required to be valid data
2h = 3 consecutive and equal samples required to be valid data
3h = 4 consecutive and equal samples required to be valid data
0h = Enable wetting current reduction (to 2mA) for 10mA and 15mA
settings upon TW event for all inputs enabled with CSO.
1h = Disable wetting current reduction (to 2mA) for 10mA and 15mA
settings upon TW event for all inputs enabled with CSO.
For detailed descriptions for the INT pin assertion scheme, refer to
section Interrupt Generation and /INT Assertion.
0h = INT pin assertion scheme set to static
1h = INT pin assertion scheme set to dynamic
