Figure 40. Data Transfer Format – Slave Transmit Transaction with 7-bit Address
Slave Transmit Transaction with 7-bit Address
The data transfer format for a Master reading data from a Slave in 7-bit address mode is
shown in Figure 40. The following procedure describes the I

1. Software configures the controller for operation as a Slave in 7-bit addressing mode as
