Hello,
I read the entire datasheet of 89V51RD2 but I am not able to locate the programming codes for the microcontroller.
I want to program it to perform an Input output operation.
What ports must I use and what should be the program structure like?
Is there Something known as Data Direction register in this IC like in ATMEL AVRs?
Regards,
Hardik
This is an ISP-programming forum, with general questions on '51s better go to http://www.8052.com/forum .
Nevertheless your questions might be answered in the 8052.com tutorial, and/or the "bible" ( = 8051 manual). The datasheet usually deals only with the items which are different from the "classic" 8051 and are specific for the given model.
