5.3.4
Notes are different in programming depending on whether a subroutine is called or not by the program in executing an
interrupt routine, whether multiple interrupts are enabled or disabled, and whether such interrupts are maskable or
non-maskable.
Status A: Maskable interrupt is being processed
Notes on Interrupt Routine
A-1: When a subroutine is not called by the program in executing an interrupt routine
A-1-1: When multiple interrupts are disabled
A-1-2: When multiple interrupts are enabled
Example of description: Status A-1-1
Intrpt_A-1-1;
•Processing immediately after the start of interrupt routine execution
•Processing at the end of interrupt routine execution
•Processing immediately after the start of interrupt routine execution
•Processing at the end of interrupt routine execution

No specific notes.
Specify the RTI instruction to return the contents of the ELR register to the PC and those of the EPSW
register to PSW.
Specify "PUSH ELR, EPSW" to save the interrupt return address and the PSW status in the stack.
Specify “POP PC, PSW” instead of the RTI instruction to return the contents of the stack to PC and
PSW.
