15.6
In master mode, this module has a possibility that high level period may be short in the two states
described below.
Therefore, it monitors SCL and communicates by bit with synchronization.
Figure 15.21 shows the timing of the bit synchronous circuit and table 15.4 shows the time when
SCL output changes from low to Hi-Z then SCL is monitored.
