11 TM The ARM Architecture - 11 Embedded Systems Lab./Honam University When an exception occurs, the core: Copies CPSR into SPSR_ Sets appropriate CPSR bits u If core implements ARM Architecture 4T and is currently in Thumb state, then n ARM state is entered. u Mode field bits u Interrupt disable flags if appropriate. Maps in appropriate banked registers Stores the “return address” in LR_ Sets PC to vector address To return, exception handler needs to: Restore CPSR from SPSR_ Restore PC from LR_ Exception Handling and the Vector Table
