RETI - Return from interrupt. The PC, W, STATUS and FSR registers are restored to the values they had when the interrupt occurred. Shadow registers are used to hold these values; the subroutine return address stack is not used. Thus subroutines can be called to a depth of eight levels while interrupts are enabled.
