This module has a possibility that the high-level period is shortened in the two states described
below.
In master mode,
• When SCL is driven low by the slave device
• When the rising speed of SCL is lowered by the load on the SCL line (load capacitance or
Therefore, this module monitors SCL and communicates bit by bit in synchronization.
Figure 17.18 shows the timing of the bit synchronous circuit, and table 17.4 shows the time when
SCL output changes from low to Hi-Z and the period which SCL is monitored.
