Pull-Up Driver Calibration
0: Calibration complete or not running.
1: Start calibration of pull up (Self clearing).
Calibration determines the lowest usable pull-up strength.
Calibration Result
0: Fail (switch may be closed preventing detection of pull ups).
Writes value of 0x11111 to PC0PCF[4:0]
1: Pass (writes calibrated value into PC0PCF[4:0]).
Calibration Port
0: Calibration on PC0 only.
1: Calibration on PC1 only.
Pull-Up Resistor Select
Current with force pull-up on bit set (PC0TH.2=1) and VBAT=3.6V.
000: Pull-up disabled.

111: 4 mA.*
*The effective average pull-up current depends on selected resistor, pull-up
resistor duty-cycle multiplier, and sample rate duty-cycle multiplier.
Pull-Up Resistor Duty Cycle Multiplier
000: 1/4 (25%)*
001: 3/8 (37.5%)*
010: 1/2 (50%)*
011: 3/4 (75%)*
*The final pull-up resistor duty cycle is the sample rate duty-cycle multiplier
times the pull-up duty-cycle multiplier.
