Writing '1' to this bit forces the proximity sensing module to use the current dithered impedance
as calibrated dithered impedance. After writing '1' to this bit, I2C should monitor the calibration
status bit ( Prox Data Port 1, bit 6). On reading '1' in calibration status bit, I2C must write '0' in
forced proximity calibration bit to complete the calibration action.
EVR used for proximity detection. typically value of 0x02-0x05 is used.
Reads '1' if calibration is completed.
Reads '0' if I2C executes a forced calibration
The data read in this location is controlled by the access mode setting in PROX_TRIG register.
