Status Affected:
Description:
Logical Left Shift
[ label ] LSLF f {,d}
0 ≤ f ≤ 127
d ∈ [0,1]
(f<7>) → C
(f<6:0>) → dest<7:1>
0 → dest<0>
C, Z
The contents of register ‘f’ are shifted
one bit to the left through the Carry flag.
A ‘0’ is shifted into the LSb. If ‘d’ is ‘0’,
the result is placed in W. If ‘d’ is ‘1’, the
result is stored back in register ‘f’.

Description:
Logical Right Shift
[ label ] LSLF f {,d}
0 ≤ f ≤ 127
d ∈ [0,1]
0 → dest<7>
(f<7:1>) → dest<6:0>,
(f<0>) → C,
C, Z
The contents of register ‘f’ are shifted
one bit to the right through the Carry
flag. A ‘0’ is shifted into the MSb. If ‘d’ is
‘0’, the result is placed in W. If ‘d’ is ‘1’,
the result is stored back in register ‘f’.

Example:
Move f
[ label ] MOVF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(f) → (dest)
Z
The contents of register f is moved to
a destination dependent upon the
status of d. If d = 0,
destination is W register. If d = 1, the
destination is file register f itself. d = 1
is useful to test a file register since
status flag Z is affected.
