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 cor-
responding registers, W, 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 W. 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’ = 1, then the
bank will be selected as per the
BSR value (default).
