16.3 (a) and (b). The first frame following a start condition always consists of 8 bits.
IIC channel 0 only is capable of formatless operation, as shown in figure 16.4.
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 16.5.
Figure 16.6 shows the I
The symbols used in figures 16.3 to 16.6 are explained in table 16.4.
