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.

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.

The contents of register ’f’ are
rotated one bit to the left through
the Carry Flag. If ’d’ is 0, the
result is placed in the W register.
If ’d’ is 1, the result is stored back
in register ’f’.
