The I
• Writing data to the IICA shift register (IICA)
• Setting bit 5 (WREL) of IICA control register 0 (IICCTL0) (canceling wait)
• Setting bit 1 (STT) of the IICCTL0 register (generating start condition)
• Setting bit 0 (SPT) of the 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 the IICA register.
To receive data after canceling a wait state, or to complete data transmission, set bit 5 (WREL) of the IICCTL0 register
To generate a restart condition after canceling a wait state, set bit 1 (STT) of the IICCTL0 register to 1.
To generate a stop condition after canceling a wait state, set bit 0 (SPT) of the IICCTL0 register to 1.
Execute the canceling processing only once for one wait state.
If, for example, data is written to the IICA register after canceling a wait state by setting the WREL bit to 1, an incorrect
In addition to the above, communication is stopped if the IICE bit is cleared to 0 when communication has been aborted,
If the I
Caution If a processing to cancel a wait state is executed when WUP = 1, the wait state will not be canceled.
