BBSY bit
Clearing of the MST bit after completion of master transmission/reception, or other
modifications of IIC control bits to change the transmit/receive operating mode or settings,
must be carried out during interval (a) in figure 16.18 (after confirming that the BBSY bit has
been cleared to 0 in the ICCR register).
Notes on Start Condition Issuance for Retransmission
Figure 16.19 shows the timing of start condition issuance for retransmission, and the timing for
subsequently writing data to ICDR, together with the corresponding flowchart. After
retransmission start condition issuance is done and determined the start condition, write the
transmit data to ICDR, as shown below.
