Reading IICS0
INTIICA0 = 1?
Use the following flows to perform the processing to release the STOP mode other than by an interrupt request
(INTIICA0) generated from serial interface IICA.
• Master device operation: Flow shown in Figure 13-24
• Slave device operation: Same as the flow in Figure 13-23
