d
See description below
C
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’.

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