Return from interrupt. Stack is popped
and Top-of-Stack (TOS) is loaded into
the PC. Interrupts are enabled by
setting either the high or low-priority
global interrupt enable bit. If ‘s’ = 1 , the
contents of the shadow registers WS,
STATUSS and BSRS are loaded into
their corresponding registers W,
STATUS and BSR. If ‘s’ = 0 , no update
of these registers occurs.
