17.14.2 When communication reservation function is disabled (IICFn.IICRSVn bit = 1)
rejected and a start condition is not generated. There are two modes in which the bus is not used
shown in Table 17-7 is required until the STCFn flag is set after setting the STTn bit to 1. Therefore, secure the time by
software.

When the IICCn.STTn bit is set when the bus is not used in a communication during bus communication, this request is
• When arbitration results in neither master nor slave operation
• When an extension code is received and slave operation is disabled (ACK is not returned and the bus was released
To confirm whether the start condition was generated or request was rejected, check the IICFn.STCFn flag. The time
when the IICCn.LRELn bit was set to 1) (n = 0, 1).
