Description
You can minimize the POR time in Cyclone® III devices by selecting between a fast POR time or a standard POR time depending on the MSEL pin settings. The fast POR time is 3 ms < TPOR < 9 ms for fast configuration time. The standard POR time is 50 ms < TPOR < 200 ms, which has a lower power-ramp rate. In both cases, you can extend the POR time by using an external component to assert the nSTATUS pin low.
You cannot disable or bypass the POR circuitry.
