313 / 398 page  2010 Microchip Technology Inc. Preliminary DS41413A-page 313 PIC12F/LF1822/16F/LF1823 REGISTER 26-1: CPSCON0: CAPACITIVE SENSING CONTROL REGISTER 0 R/W-0/0 R/W-0/0 U-0 U-0 R/W-0/0 R/W-0/0 R-0/0 R/W-0/0 CPSON CPSRM — — CPSRNG<1:0> CPSOUT T0XCS 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 CPSON: Capacitive Sensing Module Enable bit 1 = Capacitive sensing module is enabled 0 = Capacitive sensing module is disabled bit 6 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. bit 5-4 Unimplemented: Read as ‘0’ bit 3-2 CPSRNG<1:0>: Capacitive Sensing Current Range bit 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 bit 1 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) bit 0 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 FOSC/4 |
