LSLF
Logical Left Shift
Syntax:
[ label ] LSLF
f {,d}
Operands:
0
f 127
d
[0,1]
Operation:
(f<7>)
C
(f<6:0>)
dest<7:1>
0
dest<0>
Status Affected:
C, Z
Description:
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’.
LSRF
Logical Right Shift
Syntax:
[ label ] LSRF

Status Affected:
C, Z
Description:
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’.

MOVF
Move f
Syntax:
[ label ]
MOVF f,d
Operands:
0
f 127
d
[0,1]
Operation:
(f)
(dest)
Status Affected:
Z
Description:
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.
