Exception and Interrupt Handling in ARM
ic.unicamp.br2. Copy CPSR to the SPSR of new mode. 3. Change the mode by modifying bits in CPSR. 4. Fetch next instruction from the vector table. Leaving exception handler 1. Move the Link Register LR (minus an offset) to the PC. 2. Copy SPSR back to CPSR, this will automatically changes the mode back to the previous one. 3.

Exception and Interrupt Handling in ARM - UMD
classweb.ece.umd.edu• Copy CPSR to the appropriate SPSR, which is one of the banked registers for each mode of operation. • Force the CPSR mode bits to a value depending on the raised exception. • Force the PC to fetch the next instruction from the exception vector table. • Now the handler is running in the mode associated with the raised exception.
