I am using an AT89c51rc2 and want to know which include (*.h) file to use. Which should I start with?
Thanks for the explicit answer.
I have another "stupid" question: why is the name of the uC header file called reg51xd2 and not the uC name from the kompany AT89c51RC2?
"What is the significance of the "xd2" vs. the "rc2" ?" It's probably a generic include for a number of similar variants. For pity's sake, why don't you just go and download the correct file from Atmel? Look, here's a link: http://www.atmel.com/dyn/products/product_card.asp?part_id=2854 Then it'll even have the right name and the right SFRs at the right addresses. Stefan
why is the name of the uC header file called reg51xd2 and not the uC name from the kompany AT89c51RC2? because that header will cover AT89C51Rx2 and P89C51Rx2 where 'x' can be A, B, C or D. Coming to think of it Atmel also has a series with another preface than 'AT' Erik
