20.13 Wakeup Function
extension code has been received by using the slave function of the I
efficient by preventing unnecessary INTIICn signals from occurring when addresses do not match.

generated the start condition) to a slave device.

Notes 1.
The makeup function is a function that generates an interrupt request signal (INTIICn) when a local address or
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

n = 0 to 3 (V850ES/JH3-E)
n = 0 to 4 (V850ES/JJ3-E)
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.
When there is a possibility that arbitration will occur, set the SPIEn bit to 1 for master device operation
(n = 0 to 2).
