Flash Write/read

Hi.. I am trying to write/ read from the flash. I am working on an Altera DE2 board. I am just trying to write some value (8-bit) in into a fixed memory location in a flash, and am trying to read it....

Since you do have the datasheet, I can't understand why you don't read it.

Anyway:

- byte pin selects 8 or 16bit bus; this is usually hardwired high or low depending on how the flash memory is connected to your system, i.e. if you have only 8 data bits connected or all 16.

- ry/by is optional: you can get the same information reading the status bits.

The command sequences are summarized in table 16, page 37.
