PIC16F87/88
SUBLW
Syntax:
Subtract W from Literal
[ label ] SUBLW k
Operands:
0 k 255
Operation:
k – (W) W)
Status Affected: C, DC, Z
Description:
The W register is subtracted (two’s
complement method) from the
eight-bit literal ‘k’. The result is
placed in the W register.
XORLW
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR Literal with W
[ label ] XORLW k
0 k 255
(W) .XOR. k W)
Z
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.
SUBWF
Syntax:
Subtract W from f
[ label ] SUBWF f,d
Operands:
0 f 127
d [0,1]
Operation:
(f) – (W) destination)
Status Affected: C, DC, Z
Description:
Subtract (two’s complement
method) W register from register ‘f’.
If ‘d’ = 0, the result is stored in the
W register. If ‘d’ = 1, the result is
stored back in register ‘f’.
XORWF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Exclusive OR W with f
[ label ] XORWF f,d
0 f 127
d [0,1]
(W) .XOR. (f) destination)
Z
Exclusive OR the contents of the
W register with register ‘f’. If
‘d’ = 0, the result is stored in the
W register. If ‘d’ = 1, the result is
stored back in register ‘f’.
SWAPF
Syntax:
Operands:
Operation:
Status Affected:
Description:
Swap Nibbles in f
[ label ] SWAPF f,d
0 f 127
d [0,1]
(f<3:0>) (destination<7:4>),
(f<7:4>) (destination<3:0>)
None
The upper and lower nibbles of
register ‘f’ are exchanged. If
‘d’ = 0, the result is placed in W
register. If ‘d’ = 1, the result is
placed in register ‘f’.
