Return from Interrupt
[ label ]
None
TOS  PC,
1  GIE
None
Return from Interrupt. Stack is
POPed and Top-of-Stack (TOS)
is loaded in the PC. Interrupts are
enabled by setting Global
Interrupt Enable bit, GIE (INT-
CON<7>). This is a two-cycle
instruction.

Description:
Return from Subroutine
[ label ]
None
TOS  PC
None
Return from subroutine. The stack
is POPed and the top of the stack
(TOS) is loaded into the program
counter. This is a two-cycle
instruction.
Return with literal in W
[ label ]
0  k  255
k  (W);
TOS  PC
None
The W register is loaded with the
eight-bit literal ‘k’. The program
counter is loaded from the top of
the stack (the return address).
This is a two-cycle instruction.
