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.

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'.
