d
(f)
Z
The contents of register f are
moved to a destination dependant
upon the status of d. If d = 0, des-
tination is W register. If d = 1, the
destination is file register f itself.
d = 1 is useful to test a file register,
since status flag Z is affected.
Move Literal to W
[ label ]
0
k
None
The eight-bit literal ’k’ is loaded
into W register. The don’t cares
will assemble as 0’s.

k
TOS
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.
Return from Subroutine
[ label ]
None
TOS
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.
