i have built a kind of...thing with the purpose to program a Flash memory from PC parallel via a CPLD
The Cpld i used is a Xilinx xc95144 and the flash that i got scraped from surplus(maybe a dvd) is HY29LV160
I did the programming software in visual basic,and it looks that i can read correctly the Flash,at least i can read ascii strings and so on
Well,i can't understand this stuff about unlock cycles,unlock bypass and so on
what is ,for example a "command"?What is that makes it distinguishible from a data or an address?
In few words,can anybody reccomand me a link explaining in a more newbie fashion way how to treat with such devices(28F family included)?
Many thanks to you all
