R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

CPSON: Capacitive Sensing Module Enable bit
1 = Capacitive sensing module is operating
0 = Capacitive sensing module is shut off and consumes no operating current
Unimplemented: Read as ‘0’
CPSRNG<1:0>: Capacitive Sensing Oscillator Range bits
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.
CPSOUT: Capacitive Sensing Oscillator Status bit
1 = Oscillator is sourcing current (Current flowing out the pin)
0 = Oscillator is sinking current (Current flowing into the pin)
T0XCS: Timer0 External Clock Source Select bit
If T0CS = 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 T0CS = 0
Timer0 clock source is controlled by the core/Timer0 module and is FOSC/4.
