(2) When communication reservation function is disabled (bit 0 (IICRSV) of IICA flag register 0 (IICAF0) = 1)
When bit 1 (STT0) of the IICA control register 0 (IICACTL0) is set to 1 when the bus is not used in a communication
during bus communication, this request is rejected and a start condition is not generated. The following two
statuses are included in the status where bus is not used.
• 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
To confirm whether the start condition was generated or request was rejected, check the STCF flag (bit 7 of IICF0
register). It takes up to 5 clocks until the STCF flag is set to 1 after setting STT0 = 1. Therefore, secure the time by
software.
released by setting bit 6 (LREL0) of the IICACTL0 register to 1 and saving communication)
