An example of the processing procedure of the slave with the INTIIC0 interrupt is explained below (processing is
performed assuming that no extension code is used). The INTIIC0 interrupt checks the status, and the following
operations are performed.
<1> Communication is stopped if the stop condition is issued.
<2> If the start condition is issued, the address is checked and communication is completed if the address does
<3> For data transmit/receive, only the ready flag is set. Processing returns from the interrupt with the I

not match. If the address matches, the communication mode is set, wait is cancelled, and processing returns
from the interrupt (the ready flag is cleared).
