Subtract W from f

d
(f) - (W)
C, DC, Z
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'.
Subtract W from Literal
[ label ]
0
k - (W)
The W register is subtracted (2’s com-
plement method) from the eight bit lit-
eral 'k'. The result is placed in the W
register.

None
The upper and lower nibbles of regis-
ter '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'.
