check the datasheet for checking 8 or 16bit information.
OR you can try both 8 bit and 16 bit to see if anyone works.
Also, you need to confirm the chip is a good chip. |

| The image should not include Space and special characters. Just use short and regular letters only. |

Hi
The chip is 93C56 made by ST
Which chip should i select on the device list?
Maybe the problem is coming from the the device choice?

| Try 93C56A. If it does not work, then try 93C56B. |
