The I
13.4.1
The I
The first frame following a start condition always consists of 9 bits.
The serial format is a non-addressing format with no acknowledge bit. This is shown in figure
13.4.
Figure 13.5 shows the I
The symbols used in figures 13.3 to 13.5 are explained in table 13.6.
(a) FS = 0 or FSX = 0
