#95761 - Re: port structures Responding to: ???'s previous message |
Hi Andy, I used Port 0 because it is a spare port with diagnostic LEDs in my development board. Ya, all port 0 pins are pulled up and I know that an '1' needs to be written before reading the port pin. Not to mention, in this application, no datum has to be read since all the pins are used for output.
Regards, Vignesh. |
