Slave Address
Command byte: Selects
which register you are
writing to.
Data byte: Data goes into
the register set by the
command byte (to set
thresholds, configuration
masks, and sampling rate).

Slave Address
Command byte: Selects
which register you are
reading from.
Slave Address.
Repeated due to
change in data-flow
direction
Data byte: Reads from
the register set by the
command byte.
Figure 2b. SMBus Protocol: Read Byte Format
Data byte: Reads data
from the register com-
manded by the last
read-byte or write-byte
transmission; also
used for SMBus alert
response return address.
