Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
CPSON: Capacitive Sensing Module Enable bit
1
1
= Capacitive sensing module is operating
0
= Capacitive sensing module is shut off and consumes no operating current
bit 6-4
Unimplemented: Read as ‘0’
bit 3-2
CPSRNG<1:0>: Capacitive Sensing Oscillator Range bits
00
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.
bit 1
CPSOUT: Capacitive Sensing Oscillator Status bit
1
1
= Oscillator is sourcing current (Current flowing out the pin)
0
= Oscillator is sinking current (Current flowing into the pin)
bit 0
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
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 F
Timer0 clock source is controlled by the core/Timer0 module and is F
