This function makes processing more efficient by preventing unnecessary INTIICn signals from occurring when
When a start condition is detected, wakeup standby mode is set. This wakeup standby mode is in effect while
However, when a stop condition is detected, the IICCn.SPIEn bit is set regardless of the wakeup function, and this

Table 19-5. Status During Arbitration and Interrupt Request Signal Generation Timing
When the IICCn.WTIMn bit = 1, an INTIICn signal occurs at the falling edge of the ninth clock. When
the WTIMn bit = 0 and the extension code’s slave address is received, an INTIICn signal occurs at the
falling edge of the eighth clock (n = 0 to 2).
When there is a possibility that arbitration will occur, set the SPIEn bit to 1 for master device operation
(n = 0 to 2).
