For the PIC16F/LF1934/1936/1937 devices, the Capacitive Sensing Reference Mode bit (CPSRM) is not
available and the Capacitive Sensing Low Range is the only operable range for these devices. Different bit
configurations made with the CPSRNG<1:0> bits of the CPSCON0 register make the appropriate
selections within the low range only.
The Capacitive Sensing High Range is available on the PIC16F/LF1933/1938/1939 devices only.
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
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
