15.5.3.1 Package Pins View

The Package Pins View displays all columns shown in the Ports view plus the following additional columns:

• Function is the functionality of the I/O (for example, GND or ground). See the datasheet for your device for details about each function.
• Dedicated determines whether the pin is reserved for some special functionality, such as UJTAG / Analog Block / XTL pads inputs.
• VREF (Voltage referenced), if checked, assigns the selected pin as a VREF. This column only appears for devices that support VREF (IGLOOe, Fusion, ProASIC3L A3PE3000L, ProASIC3E, and Axcelerator). A device supports VREF if one or more of its I/O banks support VREF. IGLOO (excluding IGLOOe) and ProASIC3 (excluding ProASIC3L A3PE3000L and ProASIC3E) devices are not supported.
• User Reserved, if checked, reserves the pin for use in another design. When a pin is reserved, you cannot assign it to a port. To unreserve the pin, deselect the User Reserved check box.
