NAME
DESCRIPTION
0
INHIBIT_CHARGE
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.
1
ENABLE_POLLING
Not implemented
BIT
2
POR_RESET
0 = No change.
1 = Change the ChargingVoltage() to 0xFFFF and the ChargingCurrent()
to 0x00C0; clear the THERMISTOR_HOT and ALARM_INHIBITED flip-
flops.
3
RESET_TO_ZERO
Not implemented
7
Not implemented
6
POWER_FAIL_MASK
0* = Interrupt on either edge of the POWER_FAIL status bit.
1 = Do not interrupt because of a POWER_FAIL bit change.
5
BATTERY_PRESENT_ MASK
0* = Interrupt on either edge of the BATTERY_PRESENT status bit.
1 = Do not interrupt because of a BATTERY_PRESENT bit change.
4
AC_PRESENT_MASK
0* = Interrupt on either edge of the AC_PRESENT status bit.
1 = Do not interrupt because of an AC_PRESENT bit change.
12
Not implemented
11
Not implemented
10
HOT_STOP
0 = The THERMISTOR_HOT status bit does not turn off the charger.
1* = The THERMISTOR_HOT status bit does turn off the charger.
THERMISTOR_HOT is reset by either POR_RESET or
BATTERY_PRESENT = 0 status bit.
