I am using the ATMEL91SAM7SE512 controller with ARM7TDMI processor.The application is running in the User mode .

when the interrupt(IRQ) occurs processor must switch to IRQ mode,then it should go to the IRQ handler routine.

here application developer part is to tell the IRQ handler address only.so who taking the responsibility to change from User mode to IRQ mode.

whether the core itself switched into IRQ mode using hardware setup or some low level routines(program) avail.i struck in this point , i cant

proceed further on this study of ARM7TDMI processor.

please tell me your thoughts regarding this query.

I'd highly recommend the ARM System Developer's Guide book if you are interested in any of this low level platform setup; I always a copy open on my desk!
