Return from subroutine. The
stack is popped and the top of the
stack (TOS) is loaded into the
program counter. If ’s’ = 1, the
contents of the shadow registers
WS, STATUSS and BSRS are
loaded into their corresponding
registers, WREG, STATUS and
BSR. If ’s’ = 0, no update of
these registers occurs (default).

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 WREG. If 'd' is 1 the
result is stored back in register 'f'
(default). If ’a’ is 0, the Access
Bank will be selected, overriding
the BSR value. If ’a’ is 1, the Bank
will be selected as per the BSR
value.
