Table 4, ChargerStatusCmd bit map
CHARGE_INHIBITED bit reflects the status of the charger set by the INHIBIT_CHARGE bit.
POLLING ENABLED bit is set/reset in the HESC-SER charger with the ENABLE_POLLING bit of ChargerModeCmd()
set.
VOLTAGE_NOTREG bit is set when the HESC detects that the requested voltage in the ChargingVoltageCmd()
register is not in regulation. The VOLTAGE_NOTREG bit typically is set during constant current charging unless the
battery voltage reaches the value set in ChargingVoltageCmd() and the HESC begins to voltage regulate to
ChargingVoltageCmd() value. VOLTAGE_NOTREG is cleared when the HESC is regulating to the
ChargingVoltageCmd() value. VOLTAGE_NOTREG is not defined when the charger is disabled.
CURRENT_NOTREG bit is set when the HESC detects that the requested current in the ChargingCurrentCmd()
register is not in regulation. The CURRENT_NOTREG bit will typically be set during constant voltage charging unless
the battery current is near the value set in ChargingCurrentCmd() and the HESC begins to current regulate to
ChargingCurrentCmd() value. CURRENT_NOTREG is cleared when the HESC is regulating to the
ChargingCurrentCmd() value. CURRENT_NOTREG is not defined when the HESC is disabled.
