What are the types of ports available for us?. For who? Where? what is meant by quasi bi directional port?. For details relating to the generic 8051 architecture, see the documents commonly referred to as "the bible" for the 8051 - the port structure (including the quasi-bidirectional bit) are fully described: Chapter 1 - 80C51 Family Architecture: http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set: http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf These documents define the basics - you will also need to read the Datasheet for the particular chip you are using for specific details. You should also look at the Tutorials and FAQs on this site |
