What are the RUP/RDN pins on my Stratix device and how should I connect them?
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description The RUP and RDN pins were intended to be used to calibrate the on-chip series termination impedance values in Stratix® and Stratix GX devices. As Stratix and Stratix GX devices do not support series OCT, treat these pins as regular I/O pins.
