Figure 14-23. Flow When Setting WUPn = 0 upon Address Match (Including Extension Code Reception)
Use the following flows to perform the processing to release the STOP mode other than by an interrupt request
(INTIICAn) generated from serial interface IICA.
● When operating next IIC communication as master: Flow shown in Figure 14-24.
● When operating next IIC communication as slave
When released by INTIICAn interrupt: Same as the flow in Figure 14-23.
When released by other than INTIICAn interrupt: Wait for INTIICAn interrupt with WUPn left set to 1.
