CPSON
CPSON: CPS Module Enable bit
1 = CPS module is enabled
0 = CPS module is disabled
CPSRM: Capacitive Sensing Reference Mode bit
1 = CPS module is in high range. DAC and FVR provide oscillator voltage references.
0 = CPS 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 F
