Checksum for flash memory

Greetings.

If I am pulling data from the EPCS64 How many bits can I pull off it at a time 8 , 16, 32?

Is there a quick and easy way to create a checksum to check the data? I've never implimented one before and am unsure where to start. Thanks

    The EPCS64 is byte by byte. Look through the datasheet for the EPCS64 for more details. There are many ways in creating a checksum if you don't want to make a full CRC or something. I sometimes will just add all the bytes together and let it wrap around 16, 32 bit depending on the size of the checksum I want.

    Hope that helped.
