[Description]
This is a return instruction from the vectored interrupt.
The data saved in the stack returns to the PC and the PSW, and the program returns from the interrupt
service routine.
None of interrupts are acknowledged between this instruction and the next instruction to be executed.
The NMIS flag is set to 1 by acknowledgment of a non-maskable interrupt, and cleared to 0 by the RETI
instruction.
[Caution]
When the return from non-maskable interrupt servicing is performed by an instruction other than the RETI
instruction, the NMIS flag is not cleared to 0, and therefore no interrupts (including non-maskable interrupts) can
be acknowledged.
