Add Literal and W

[ label ] ADDLW k

0 ≤ k ≤ 255

(W) + k → (W)

C, DC, Z

11 111x kkkk kkkk

The contents of the W register are

added to the eight bit literal ’k’ and the

result is placed in the W register.

d ∈ [0,1]

(W) + (f) → (dest)

C, DC, Z

00 0111 dfff ffff

Add the contents of the W register

with 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’.
