This command terminates an interrupt handling routine. Normal program flow will be continued then.
This command is intended for use in standalone mode only.
An interrupt routine must always end with a RETI command. Do not allow the normal program flow to run
into an interrupt routine.
Internal function: The saved registers (accumulator, X registers, flags and program counter) are copied
back so that normal program flow will continue.
