k - (W)
C, DC, Z
The W register is subtracted (2’s
complement method) from the eight-
bit literal 'k'. The result is placed in the
W register.

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'.
