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.

Rotate Right f through Carry
[ label ]

d
See description below
C
The contents of register ‘f’ are
rotated one bit to the right through
the Carry flag. If ‘d’ = 0, the result
is placed in the W register. If
‘d’ = 1, the result is placed back in
register ‘f’.
Rotate Left f through Carry
[ label ]
0
d
See description below
C
The contents of register ‘f’ are
rotated one bit to the left through
the Carry flag. If ‘d’ = 0, the result
is placed in the W register. If
‘d’ = 1, the result is stored back in
register ‘f’.
