register ‘f’
Rotate Left f (No Carry)

N, Z
The contents of register, ‘f’, are rotated
one bit to the left. If ‘d’ is ‘0’, the result is
placed in W. If ‘d’ is ‘1’, the result is
stored back in register, ‘f’. If ‘a’ is ‘0’, the
Access Bank will be selected, overrid-
ing the BSR value. If ‘a’ is ‘1’, then the
bank will be selected as per the BSR
value.

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
W. If ‘d’ is ‘1’, the result is placed back
in register, ‘f’. If ‘a’ is ‘0’, the Access
Bank will be selected, overriding the
BSR value. If ‘a’ is ‘1’, then the bank will
be selected as per the BSR value.
