CPSON: Capacitive Sensing Module Enable bit

1 = Capacitive sensing module is enabled

0 = Capacitive sensing module is disabled

CPSRM: 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 the low range. Internal oscillator voltage references are used.

Unimplemented: Read as ‘0’

CPSRNG<1:0>: Capacitive Sensing Current Range bits

If CPSRM = 0 (low range):

00 = Oscillator is off

01 = Oscillator is in Low Range. Charge/Discharge Current is nominally 0.1 µA

10 = Oscillator is in Medium Range. Charge/Discharge Current is nominally 1.2 µA

11 = Oscillator is in High Range. Charge/Discharge Current is nominally 18 µA

If CPSRM = 1 (high range):

00 = Oscillator is on. Noise Detection mode. No Charge/Discharge current is supplied.

01 = Oscillator is in Low Range. Charge/Discharge Current is nominally 9 µA

10 = Oscillator is in Medium Range. Charge/Discharge Current is nominally 30 µA

11 = Oscillator is in High Range. Charge/Discharge Current is nominally 100 µA

CPSOUT: 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)

T0XCS: Timer0 External Clock Source Select bit

If TMR0CS = 1:

The T0XCS bit controls which clock external to the core/Timer0 module supplies Timer0:

1 = Timer0 clock source is the capacitive sensing oscillator

0 = Timer0 clock source is the T0CKI pin

If TMR0CS = 0:

Timer0 clock source is controlled by the core/Timer0 module and is FOSC/4
