Write Byte Format
Read Byte Format
Send Byte Format
Receive Byte Format
Slave address: equiva-
lent to chip-select line of
a 3-wire interface
Command byte: selects to
which register you are writing
Data byte: data goes into the register
set by the command byte (to set
thresholds, configuration masks, and
sampling rate)
Slave address: equivalent
to chip-select line
Command byte: selects
from which register you
are reading
Slave address: repeated
due to change in data-
flow direction
Data byte: reads from
the register set by the
command byte
Command byte: sends com-
mand with no data, usually
used for one-shot command
Data byte: reads data from
the register commanded
by the last read byte or
write byte transmission;
also used for SMBus alert
response return address
S = Start condition
Shaded = Slave transmission
P = Stop condition
