CHxCAL: Each channel has three calibration bits, which adds 2.5 mV of offset per bit (2.5 mV to 17.5 mV) to the switch current sense voltage threshold. The calibration bits can decrease the offset mismatch between the switch current sense of the two channels and improve the current sharing in two phase applications.
CHxGOFF: This bit turns off the associated channel, when set to "1".
