0* = Allow normal operation; clear the CHG_INHIBITED flip-flop.
1 = Turn off the charger; set the CHG_INHIBITED flip-flop.
The CHG_INHIBITED flip-flop is not affected by any other commands.
Not implemented
0 = No change.
1 = Change the ChargingVoltage() to 0xFFFF and the ChargingCurrent()
Not implemented
0* = Interrupt on either edge of the AC_PRESENT status bit.
1 = Do not interrupt because of an AC_PRESENT bit change.
0* = Interrupt on either edge of the BATTERY_PRESENT status bit.
1 = Do not interrupt because of a BATTERY_PRESENT bit change.
0* = Interrupt on either edge of the POWER_FAIL status bit.
1 = Do not interrupt because of a POWER_FAIL bit change.
