Why do the BSEL/CSEL pull-up and pull-down resistor values in Cyclone V Device Schematic Review Worksheet not match with the Cyclone V Device Family Pin Connection Guidelines?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

In the Cyclone® V Schematic Review Worksheet version 4.0, it states that the pull-up and pull-down resistor values for BSEL/CSEL should be 4.7-kΩ and 10-kΩ which contradicts the information in the Cyclone® V Device Family Pin Connection Guidelines version 2.6 which recommends connecting a pull-up such as 10-kΩ or pull-down resistor such as 1-kΩ to select the desired boot select values. Please follow Pin Connection Guidelines recommendation. 

 

Resolution

The Cyclone® V Schematic review worksheet will be updated in future release to recommend resistor values of 1-kΩ pull down and 10-kΩ pull up for the BSEL/CSEL pins.
