Description:
Subtract W from f
[label]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) - (W) → (dest)
C, DC, Z
00
Subtract (2’s complement method)
W register from register ‘f’. If ‘d’ is
‘0’, the result is stored in the W
register. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.
C = 1; result is positive or zero
C = 0; result is negative
Subtract W from Literal
[label]
0 ≤ k ≤ 255
k - (W) → (W)
C, DC, Z
11
The W register is subtracted (2’s
complement method) from the
eight-bit literal ‘k’. The result is
placed in the W register.
C = 1; result is positive or zero
C = 0; result is negative
Swap Nibbles in f

0 ≤ f ≤ 127

None
00
The upper and lower nibbles of
register ‘f’ are exchanged. If ‘d’
is ‘0’, the result is placed in W
register. If ‘d’ is ‘1’, the result is
placed in register ‘f’.

The instruction is supported for
code compatibility with the
PIC16C5X products. Since TRIS
registers are readable and
writable, the user can directly
address them.

To maintain upward compati-
bility with future PIC

instruction.
Exclusive OR Literal with W

0 ≤ k ≤ 255
(W) .XOR. k → (W)
Z
11
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed
in the W register.
