Section 16 I
16.5
There are six interrupt requests in this module; transmit data empty, transmit end, receive data full,
NACK detection, STOP recognition, and arbitration lost. Table 16.3 shows the contents of each
interrupt request.

16.6
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 16.18 shows the timing of the bit synchronous circuit, and Table 16.4 shows the time when
SCL output changes from low to Hi-Z and the period which SCL is monitored.
