Primary Status Flags Register (FLGS1)
The FLGS1 register (address=01h) contains the primary
bq2013H flags.
The
charge status
flag (CHGS) is asserted when a
valid charge rate is detected. The bq2013H deems the
charge valid if it results in two NAC updates with V
> 250
μ
V. A V
SRO
of less than 250
μ
V or discharge activity
clears CHGS.

The
battery replaced
flag (BRP) is asserted whenever
the bq2013H is reset by application of V
or by a serial
port command. BRP is reset when either a valid charge
action increments NAC to be equal to LMD, or when a
valid charge action is detected after the EDV1 flag is
asserted. BRP = 1 signifies that the device has been re-
set.

The first

flag (EDV1)
warns the user that the battery is empty. SEG1 blinks
at a 4Hz rate and DONE is asserted low. EDV1 detec-
tion is disabled if OVLD = 1. The EDV flag is latched
until a valid charge has been detected.

The

old.
