XCore Exchange

I use XU208-128-QF48 to implement USB Audio.

The pins of XU208 is not enough for our design requirement, So I want to reuse some of the pins.

Port 8A and Port 8B are allocated as USB ports：

<Port Location="XS1_PORT_8A" Name="PORT_USB_TXD"/>
<Port Location="XS1_PORT_8B" Name="PORT_USB_RXD"/>

Port 4B is part of Port 8A，Can I allocated Port 4B as GPIO？

According to the Document xCORE-200-Devices-Package-and-Portmap_11.xls， It is ok .
But I am not sure, Please help me to make sure it. Thank you!

Hi. If the background of the port label in this spread sheet is WHITE then the port is available so yes, 4A is available.

So are ports 4B, 4C, 4D.

Got it. Thank you for your fast reply.
