Format
Figure 26.3 shows the format of data transfer from a master to a slave device (master data transmit
format). Figure 26.4 shows the data transfer format (master data receive format) when a master
device reads the second and the following byte data from a slave device.
From MASTER to SLAVE
From SLAVE to MASTER
A = ACKNOWLEDGE (SDA LOW)
A = NOT ACKNOWLEDGE (SDA HIGH)
S = Strat condition

Figure 26.4 Master Data Receive Format
Figure 26.5 shows the combined format when the data transfer direction changes during one
transfer. When changing the direction after the first transfer, the repeated START condition (Sr),
slave address and R/W bits are transmitted. In this case, the R/W bit is set to the direction opposite
to the first transfer direction. The repeated START condition is issued by the master at the end of a
transmit or receive cycle if the enable start generation bit in the master control register has been
set.
