bq2050 Registers
The bq2050 command and status registers are listed in
Table 7 and described below.
Command Register (CMDR)
The write-only CMDR register is accessed when eight
valid command bits have been received by the bq2050.
The CMDR register contains two fields:
W/R bit
Command address
The W/R bit of the command register is used to select whether
thereceivedcommandisforareadorawritefunction.
The W/R values are:

The following eight bits should be written
to the register specified by the address por-
tion of CMDR.
The lower seven-bit field of CMDR contains the address
portion of the register to be accessed. Attempts to write
to invalid addresses are ignored.
Primary Status Flags Register (FLGS1)
The read-only FLGS1 register (address=01h) contains
the primary bq2050 flags.
The
charge status
flag (CHGS) is asserted when a
valid charge rate is detected.

The
battery replaced
flag (BRP) is asserted whenever
the bq2050 is reset either by application of V
CC
or by a
serial port command. BRP is reset when either a valid
charge action increments NAC to be equal to LMD, or a
valid charge action is detected after the EDV1 flag is as-
serted. BRP = 1 signifies that the device has been reset.
The BRP values are:
Where BRP is:
0
Battery is charged until NAC = LMD or dis-
charged until the EDV1 flag is asserted
