Can a long rise time on CONF_DONE cause configuration to fail?
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description If the rise time of CONF_DONE is too slow, the FLEX device could register CONF_DONE while it is transitioning, causing the device's internal statemachine to enter an illegal state. To avoid this illegal state, make sure the CONF_DONE signal has a fast rise time by placing a smaller pull-up resistor on the signal. This solution applies to all configuration modes.
