#35281 - P89C557E4 |
Does someone have some more info about this device?
I am in possesion of a philips datasheet, there is no indication of a way to initialize the ports. All my P0 ports have square waves on them, and the others are all 1 and I can't seem to change it. Could be a hardware problem , I'm just trying to rule out software probs'. |
