Can you set the Power-on Reset (POR) time in Cyclone devices?
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description No, Cyclone® devices do not have a PORSEL pin therefore, the POR delay is governed by the Cyclone device (typically 100 ms). During initial power-up, a POR delay occurs to ensure the system voltage levels have stabilized. During Active Serial (AS) configuration, the Cyclone device controls the configuration and has a longer POR delay than the serial configuration device.
