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
(default).
