#65408 - Defining I/O pin |
I am a newbie at this, please be nice ;)
I want to set up my first 8052 program(in ANSI C compiler) to simply toggle a led. I'm using port 3, which is, as far as i know, located at memory address 0xB0. So if i'm getting this right, i can simply write the value 0x01/0x00 to that adress using pointers to toggle pin 3.0 . What I actually want to know is how I can define this pin to be output. I know it must be defined somehow, but I can't find it in the datasheet. Is there a standard 8052 adress where pins are defined? For those who want to know, I'm talking about the TUSB3410 (Texas Instruments) chip here. |
