The I
• Writing data to IICA shift register (IICA)
• Setting bit 5 (WREL) of IICA control register 0 (IICCTL0) (canceling wait)
• Setting bit 1 (STT) of IICCTL0 register (generating start condition)
• Setting bit 0 (SPT) of IICCTL0 register (generating stop condition)
When the above wait canceling processing is executed, the I
To cancel a wait state and transmit data (including addresses), write the data to IICA.
To receive data after canceling a wait state, or to complete data transmission, set bit 5 (WREL) of IICA control
To generate a restart condition after canceling a wait state, set bit 1 (STT) of IICCTL0 to 1.
To generate a stop condition after canceling a wait state, set bit 0 (SPT) of IICCTL0 to 1.
Execute the canceling processing only once for one wait state.
If, for example, data is written to IICA after canceling a wait state by setting WREL to 1, an incorrect value may be
In addition to the above, communication is stopped if IICE is cleared to 0 when communication has been aborted,
