 		 #52476 - RE: update pins on a port on the byte level
Responding to: ???'s previous message
hi spancer,

take benefit of following equation


a XOR b = a.b'+a'.b

if you put b = 1 (true into it) it becomes


a xor 1 = a'

and putting b = 0 gives

a XOR 0 = a

picture is clear just prepare a byte having '1's at the places which you want to invert and remainig bits zero into the accumulator. and a simple

XRL Px,a

will do the job.
