(2) When communication reservation function is disabled (bit 0 (IICRSV) of IICA flag register 0 (IICAF0) =
1)
When bit 1 (STT0) of 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.
To confirm whether the start condition was generated or request was rejected, check STCF (bit 7 of IICF). It
takes up to 5 clocks until STCF is set to 1 after setting STT0 = 1. Therefore, secure the time by software.
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 by setting bit 6 (LREL0) of IICACTL0 to 1 and saving communication)
