#74421 - Port 0 of at89s51 |
Hi, I am currently facing a problem with at89s51's port 0. From the datasheet, an initial boot will cause port 0 to default with all 1's on it's pins, but it is not behaving so. I have look through the datasheet and tried disabling(setting) bit 0 of AUXR.
But it doesen't work. Please advice, thank you. |
