Figure 47. Data Transfer Format - Slave Receive Transaction with 7-Bit Address
Slave Transaction Diagrams
In the following transaction diagrams, shaded regions indicate data transferred from the
Master to the Slave and unshaded regions indicate data transferred from the Slave to the
Master. The transaction field labels are defined as follows:

Slave Receive Transaction with 7-Bit Address
The data transfer format for writing data from Master to Slave in 7-bit address mode is
shown in
operating as a Slave in 7-bit addressing mode, receiving data from the bus Master.
