munication timing specification and illustration sec-
tions.
Communication with the bq2013H is always performed
with the least-significant bit being transmitted first. Fig-
ure 3 shows an example of a communication sequence to
read the bq2013H NACH register.
bq2013H Command Code and
Registers
The bq2013H status registers are listed in Table 9 and
described below.
Command Code
The bq2013H latches the command code when eight
valid command bits have been received by the bq2013H.
The command code register contains two fields:
I
W/R bit
I
Command address
The W/R bit of the command code is used to select
whether the received command is for a read or a write
function.
The W/R location is:

The bq2013H outputs the requested regis-
ter contents specified by the address por-
tion of command code.

The following eight bits should be written
to the register specified by the address por-
tion of command code.
The lower seven-bit field of command code contains the
address portion of the register to be accessed. Attempts
to write to invalid addresses are ignored.
