Section 16 I
16.4
The I
16.4.1
The I
The first frame following a start condition always consists of 9 bits.
IIC_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. 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 16.6.
