(1) If RSNS bit is FUNCTION_CTL = 1, then the corresponding voltage threshold is divided by 2.
SCCD (b7-b4): These upper nibble bits select the value of the short circuit in charge delay time. Exceeding the short circuit in charge
voltage threshold for longer than this period turns off the CHG and DSG outputs. 0000 is the default.
