Is there any 8051 based microcontroller available which allows programmer to dynamically alter the pin function. That is Input and Output setting of the pins. You're not new to this forum - you should know this by now! The standard 8051 IO pins are always "Quasi-Bidirectional" - there is no way to specifically configure them as "input" or "output" http://www.8052.com/faqs.phtml?FAQ=121619 Note that some modern derivatives do provide different types of IO - but you'd have to read the specific Datasheet for details... |
