The contents of register ’f’ are
rotated one bit to the left. If ’d’ is 0
the result is placed in WREG. If ’d’
is 1, the result is stored back in reg-
ister 'f' (default). If ’a’ is 0, the
Access Bank will be selected, over-
riding the BSR value. If ’a’ is 1,
then the bank will be selected as
per the BSR value (default).
