bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7 CPSxON: Capacitive Sensing Module Enable bit
1 = Capacitive sensing module is enabled
0 = Capacitive sensing module is disabled
bit 6 CPSxRM: 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 low range. Internal oscillator voltage references are used.
bit 5-4 Unimplemented: Read as ‘0’
bit 3-2 CPSxRNG<1:0>: Capacitive Sensing Current Range bits
If CPSxRM =
0 (low range):
11 = Oscillator is in high range: Charge/discharge current is nominally 18 µA.
10 = Oscillator is in medium range. Charge/discharge current is nominally 1.2 µA.
01 = Oscillator is in low range. Charge/discharge current is nominally 0.1 µA.
00 = Oscillator is off.
If CPSxRM =
1 (high range):
11 = Oscillator is in high range: Charge/discharge current is nominally 100 µA.
10 = Oscillator is in medium range. Charge/discharge current is nominally 30 µA.
01 = Oscillator is in low range. Charge/discharge current is nominally 9 µA.
00 =Oscillator is on; Noise Detection mode; No charge/discharge current is supplied.
bit 1 CPSxOUT: 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)
bit 0 TxXCS: TimerA/B External Clock Source Select bit
If TMRxCS =
1:
The TxXCS bit controls which clock external to the core/TimerA/B module supplies TimerA/B:
1 = TimerA/B clock source is the capacitive sensing oscillator
0 = TimerA/B clock source is the TxCKI pin
If TMRxCS =
0:
TimerA/B clock source is controlled by the core/TimerA/B module and is FOSC/4.
