I am very new to the ARM, we are using the TWR-K60N512 in engineering class and we are using assembly language in codewarrior 10.1, I can not find in the oodles and oodles of documentation anything that can help me write to or read from the I/O ports? On the TWR-K60N512 I see that the LEDS are tied to PTA11, PTA28, PTA29 and PTA10. I know there has to be a SFR of some sort but I have spent hours reading through documents and have found nothing.
First question is how do I write and read from the ports? If possible please help in assembly language terminology
Second question would be how do I set the ports for input and output?
Thank you very much for your help it is much appreciated
