Exceptions/Interrupts
(2) Interrupt Level Register (ILEV)
(3) Returning without ERET instruction
settings of in Status<ERL>, Status<EXL> and SSCR<CSS> are the same as when the exception/ interrupt is
generated. Change the settings if needed.
“0” to ILEV<MLEV> to shift to the level of the previous interrupt because it does not automatically shift by an
ERET instruction. If you want to set a new value to ILEV<CMASK>, set “1” to ILEV<MLEV> and write a value
to ILEV<CMASK> simultaneously.
The following is required only for a hardware interrupt.
If the interrupt occurs, its interrupt level is set to ILEV<CSS> of the ILEV register in INTC as a mask level. Write
You can return from exception handler to a normal program without using an ERET instruction. In this case,
