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 f {,d}
Operands: 0
 f  127
d
[0,1]
Operation: 0
 dest<7>
(f<7:1>)
 dest<6:0>,
(f<0>)
 C,
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.
