CPSxON: Capacitive Sensing Module Enable bit
1 = Capacitive sensing module is enabled
0 = Capacitive sensing module is disabled
CPSxRM: Capacitive Sensing Reference Mode bit
1 = Capacitive sensing module is in high range. DAC and FVR provide oscillator voltage references.
0 = Capacitive sensing module is in low range. Internal oscillator voltage references are used.
Unimplemented: Read as ‘0’
CPSxRNG<1:0>: Capacitive Sensing Current Range bits
If CPSxRM = 0 (low range):
11 = Oscillator is in high range: Charge/discharge current is nominally 18 µA.
10 = Oscillator is in medium range. Charge/discharge current is nominally 1.2 µA.
01 = Oscillator is in low range. Charge/discharge current is nominally 0.1 µA.
00 = Oscillator is off.
If CPSxRM = 1 (high range):
11 = Oscillator is in high range: Charge/discharge current is nominally 100 µA.
10 = Oscillator is in medium range. Charge/discharge current is nominally 30 µA.
01 = Oscillator is in low range. Charge/discharge current is nominally 9 µA.
00 =Oscillator is on; Noise Detection mode; No charge/discharge current is supplied.
CPSxOUT: Capacitive Sensing Oscillator Status bit
1 = Oscillator is sourcing current (Current flowing out of the pin)
0 = Oscillator is sinking current (Current flowing into the pin)
TxXCS: TimerA/B External Clock Source Select bit
If TMRxCS = 1:
The TxXCS bit controls which clock external to the core/TimerA/B module supplies TimerA/B:
1 = TimerA/B clock source is the capacitive sensing oscillator
0 = TimerA/B clock source is the TxCKI pin
If TMRxCS = 0:
TimerA/B clock source is controlled by the core/TimerA/B module and is FOSC/4.
