15-3 (a) and (b). The first frame following a start condition always consists of 8 bits.
The serial format is a non-addressing format with no acknowledge bit. Although start and stop
conditions must be issued, this format can be used as a synchronous serial format. This is shown in
figure 15-4.
Figure 15-5 shows the I
The symbols used in figures 15-3 to 15-5 are explained in table 15-4.
