19.4.6
Figure 19.3 shows the format of data transfer from the master to the slave device (master data
transmit format). Figure 19.4 shows the data transfer format (master data receive format) in which
the master device read data on and after the second byte from the slave device.
Figure 19.5 shows the combination transfer format in which the data transfer direction changes
during one transfer.
When changing the direction at the first transfer, retransmit command (Sr), the slave address and
the R/W signal are transmitted. In this case, the R/W signal is set to the direction opposite to the
first transfer direction.
Note: * Transfer direction of data and acknowledge bits depend on R/W bits.
