In my code i kept the controller into stop3 mode. its not coming out of stop mode through SCI interrupt.its working with RTC.but we need the wake up by SCI interrupt.is wakeup is possible through SCI interrupt.
Which CPU? Coldfire 1, 2, 3 or 4?
Assuming you're using something like an MCF51CN128, do you have RXEDGIE set properly?
22.214.171.124 Stop Mode OperationDuring all stop modes, clocks to the SCI module are halted....The receive input active edge detect circuit remains activein stop3 mode, but not in stop2. An active edge on thereceive input brings the CPU out of stop3 mode if theinterrupt is not masked (RXEDGIE = 1).
Setting RXEDGIE Can make it work, wake up is possible. I faced one more issue after setting it, the TX interrupts are not being generated. All settings are really correct (checked using BDM), still dont know why TX interrupt doesnot come?
Any Idea on this ?
No, sorry. Have you tried reprogramming the SCI from scratch?
