Configuration PROMs For FPGAs FAQ

How is the reset polarity configured?

The polarity of the RESET/OE pin can be programmed by the user during the programming process using four specific EEPROM bytes.

What is the function of the nCASC pin?

The nCASC output goes Low when the address counter reaches its maximum value, allowing it to drive the nCS input of the next device in a daisy-chain configuration.
