Ip megafunction license

sorry i have no guide for you, but cfi memory is like accessing any other tri stated memory or device. like sram or a axternal uart, pio ...

don't worry that you try to access a cfi flash, just think it is just an external memory.

you need adr line,

data in and out bring them together as inout / bidir ..

and of course chip select and read/write control

you need a fsm that controls your access state (setup, access, hold) so that you enshure you meet the timing.

that is realy pretty straight foreward...
