Is there anything I need to do regarding the interrupt processing?

Latest Updated:01/18/2008

Question:

I'm using a product with a subclock. After directly transistioning between high-speed mode and subactive mode, direct transistion interrupt processing starts. Is there anything I need to do regarding the interrupt processing? (Are functions possible without the processing?)

Answer:

No register setting changes, etc. are necessary, but don't forget RTE instructions for returning from exception handling routines.
