(13) Bus status detector

This circuit detects whether or not the bus is released by detecting start conditions and stop conditions.

However, as the bus status cannot be detected immediately following operation, the initial status is set by the

STCEN0 bit.

Remark STT0 bit: Bit 1 of IICA control register 00 (IICCTL00)

SPT0 bit: Bit 0 of IICA control register 00 (IICCTL00)

IICRSV0 bit: Bit 0 of IICA flag register 0 (IICF0)

IICBSY0 bit: Bit 6 of IICA flag register 0 (IICF0)

STCF0 bit: Bit 7 of IICA flag register 0 (IICF0)

STCEN0 bit: Bit 1 of IICA flag register 0 (IICF0)
