Description:

Rotate Left f (No Carry)

[ label ] RLNCF f [,d [,a]]

0  f  255

d  [0,1]

a  [0,1]

(f<n>)  dest<n + 1>,

N, Z

0100 01da ffff ffff

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.
