Data Commands
RSVD (Bits 7–3): Reserved. Do not use.
ALERT (Bit 2): ALERT output triggered
0 = ALERT is not active.
1 = ALERT is active.
RSVD (Bit 1): Reserved. Do not use.
DSG (Bit 0): Discharge current detection
0 = No discharge is detected.
1 = Discharge current is detected.
11.8 BatteryAlert() 0x0B
This read-only register provides indications on the cause of the ALERT pin trigger. An ALERT bit only
clears if the condition for it is removed. Reading this register causes the ALERT pin to deassert and also
clears the ALERT bit in BatteryStatus(). Note the ALERT pin is only asserted if it is configured to do so for
a particular condition.

LEGEND: R/W = Read/Write; R = Read only; -n = value after reset
BATLOW (Bit 7): ALERT is triggered because of BATLOW.
TEMPLOW (Bit 6): ALERT is triggered because of TEMPLOW.
TEMPHIGH (Bit 5): ALERT is triggered because of TEMPHIGH.
SOH_LOW (Bit 4): ALERT is triggered because of SOHLOW.
EOS (Bit 3): ALERT is triggered because of EOS.
RSVD (Bit 2): Reserved. Do not use.
G_DONE (Bit 1): ALERT is triggered because of G_DONE.
INITCOMP (Bit 0): ALERT is triggered because of INITCOMP.
11.9 Current(): 0x0C/0x0D
This read-only command pair returns a signed integer value that is the average current flowing through the
sense resistor. It is updated every 1 second with units of 1 mA per bit.
11.10 ScaledR(): 0x16/0x17
This read-only command pair returns an integer value of the scaled resistance of the cell. It is updated
upon a new resistance update in EOS mode only with a resolution of 1 mΩ per bit.
11.11 MeasuredZ(): 0x22/0x23
This read-only command pair returns an integer value of the measured impedance of the cell. It is updated
upon a new resistance update in EOS mode only with a resolution of 1 mΩ per bit.
11.12 InternalTemperature(): 0x28/0x29
This read-only command pair returns an unsigned integer value of the internal temperature sensor in units
of 0.1°K, measured by the device, and has a range of 0 to 6553.5°K.
