15.5.9 Address match detection method
set to the slave address register (SVA) matches the slave address sent by the master device, or when an extension code
has been received.
15.5.10 Error detection
(IICA) of the transmitting device, so the IICA data prior to transmission can be compared with the transmitted IICA data to
enable detection of transmission errors. A transmission error is judged as having occurred when the compared data
values do not match.

C bus mode, the master device can select a particular slave device by transmitting the corresponding slave address.
C bus mode, the status of the serial data bus (SDA0) during data transmission is captured by the IICA shift register

clock. The local address stored in the slave address register (SVA) is not affected.
the SVA register is set to 11110xx0. Note that INTIICA occurs at the falling edge of the eighth clock.
• Higher four bits of data match: EXC = 1
• Seven bits of data match:
Remark
such processing is performed by software.
If the extension code is received while a slave device is operating, then the slave device is participating in
communication even if its address does not match.
For example, after the extension code is received, if you do not wish to operate the target device as a slave device,
set bit 6 (LREL) of the IICA control register 0 (IICCTL0) to 1 to set the standby mode for the next communication
operation.
