19.9 Address Match Detection Method
been set to the SVAn register and when the address set to the SVAn register matches the slave address sent by the
master device, or when an extension code has been received (n = 0 to 2).
19.10 Error Detection
of the transmitting device, so the data of the IICn register prior to transmission can be compared with the transmitted IICn
data to enable detection of transmission errors. A transmission error is judged as having occurred when the compared
data values do not match (n = 0 to 2).

Address match detection is performed automatically by hardware. The INTIICn signal occurs when a local address has

(1) When the higher 4 bits of the receive address are either 0000 or 1111, the extension code flag (IICSn.EXCn bit) is

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 pin (SDA0n) during data transmission is captured by the IICn register
set for extension code reception and an interrupt request signal (INTIICn) is issued at the falling edge of the eighth
clock (n = 0 to 2).
The local address stored in the SVAn register is not affected.

For example, when operation as a slave is not desired after the extension code is received, set the IICCn.LRELn
bit to 1 and the CPU will enter the next communication wait state.
