Preserving sectors in an EPCS

Well the reason I asked was to propose some alternatives. Seems like a lots of hassle for 8 bytes of data. You could ...

1 - Remove the ASMI megafunction and let the NIOS write those values to the flash for you through the EPCS controller. You'd have to send a signal to the NIOS to let it know when you wanted it to write the data. And of course you'd have to write the little bit of C-code involved. This allows you to keep the NIOS in your permanent FPGA image. Also, I highly suspect you'd find other uses for the NIOS along the way. Once I started putting embedded processors in my FPGA designs, I became addicted. You'll never get as much use out of so few logic gates as with an embedded processor.

2 - Add an EEPROM to the board for your parameter storage.

Anyway, you know what you're doing. I'm just giving some ideas.
