Description: Unlatched value of flags which can be selected to be latched (using Alarm Enable()) and used to assert the ALERT pin.
Bit | Field | Description |
---|---|---|
15 | SSA | This bit is set when a bit in Safety Status A() is set. 0 = Flag is not set 1 = Flag is set |
14 | SSB | This bit is set when a bit in Safety Status B() is set. 0 = Flag is not set 1 = Flag is set |
13 | SAA | This bit is set when a bit in Safety Alert A() is set. 0 = Flag is not set 1 = Flag is set |
12 | SAB | This bit is set when a bit in Safety Alert B() is set. 0 = Flag is not set 1 = Flag is set |
11 | XCHG | This bit is set when the CHG driver is disabled. 0 = Flag is not set 1 = Flag is set |
10 | XDSG | This bit is set when the DSG driver is disabled. 0 = Flag is not set 1 = Flag is set |
9 | SHUTV | This bit is set when either a cell voltage has been measured below Shutdown Cell Voltage, or the stack voltage has been measured below Shutdown Stack Voltage. The bit is cleared when written with a "1". A bit set here causes the ALERT pin to be
asserted low.
0 = Flag is not set 1 = Flag is set |
8 | CB | This bit is set when cell balancing is active. 0 = Flag is not set 1 = Flag is set |
7 | FULLSCAN | This bit pulses high briefly when a full scan is complete (including cell voltages, top-of-stack voltage, temperature, and diagnostic measurements). |
6 | ADSCAN | This bit pulses high briefly when a voltage ADC measurement scan is complete (this includes the cell voltage measurements and one additional measurement). |
5 | WAKE | This bit pulses high briefly when the device is wakened from SLEEP mode. |
4 | SLEEP | This bit pulses high briefly when the device enters SLEEP mode. 0 = Flag is not set 1 = Flag is set |
3 | TIMER_ALARM | This bit pulses high briefly when the programmable timer expires. |
2 | INITCOMP | This bit pulses high briefly when the device has completed the startup measurement sequence (after powerup or reset or exit of CONFIG_UPDATE mode or exit of DEEPSLEEP). |
1 | CDRAW | This bit is set when the CHG Detector output is set, indicating that the CHG pin has been detected above a level of approximately 2 V. 0 = CHG Detector output is not set 1 = CHG Detector output is set |
0 | POR | This bit is set if the POR bit in Battery Status is asserted. 0 = Flag is not set 1 = Flag is set |
