RLF
Syntax:
Rotate Left f through Carry
[ label ]
RLF f,d
Operands:
Operation:
0 ≤ f ≤ 31
d ∈ [0,1]
See description below
Status Affected: C
Encoding:
0011 01df ffff
Description:
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 the W register. If ’d’ is
1, the result is stored back in regis-
ter ’f’.
C
register ’f’
