When the above wait canceling processing is executed, the I
To cancel a wait state and transmit data (including addresses), write the data to IIC0.
To receive data after canceling a wait state, or to complete data transmission, set bit 5 (WREL0) of the IIC0 control
To generate a restart condition after canceling a wait state, set bit 1 (STT0) of IICC0 to 1.
To generate a stop condition after canceling a wait state, set bit 0 (SPT0) of IICC0 to 1.
Execute the canceling processing only once for one wait state.
If, for example, data is written to IIC0 after canceling a wait state by setting WREL0 to 1, an incorrect value may be
In addition to the above, communication is stopped if IICE0 is cleared to 0 when communication has been aborted,

there is a match with the address set to slave address register 0 (SVA0).
At this point, ACK is generated regardless of the value set to IICC0’s bit 2 (ACKE0). For a slave device
that has received an extension code, INTIIC0 occurs at the falling edge of the eighth clock.
However, if the address does not match after restart, INTIIC0 is generated at the falling edge of the 9th
clock, but wait does not occur.

The numbers in the table indicate the number of the serial clock’s clock signals. Interrupt requests and
wait control are both synchronized with the falling edge of these clock signals.
