14.7.1
The IIC2 is enabled or disabled by setting the module stop control register. In the initial state, the
IIC2 is disabled. After the module stop mode is canceled, registers can be accessed. For details,
see section 22, Power-Down Modes.
14.7.2
Confirm the ninth falling edge of the clock before issuing a stop or a repeated start condition.
The ninth falling edge can be confirmed by monitoring the SCLO bit in the I
2 (ICCR2).
If a stop or a repeated start condition is issued at a certain timing in either of the following cases,
the stop or repeated start condition may be issued incorrectly.
• The rising time of the SCL signal exceeds the time given in section 14.6, Bit Synchronous
• The bit synchronous circuit is activated because a slave device holds the SCL bus low during
14.7.3

If the WAIT bit is set to 1, when a slave device holds the SCL signal low more than one transfer

given period.
