Quick question greyed out IO on XU208

All,

Hope everyone is safe and healthy!

Working on a new product and see in the XU208 manual the following basic IO are greyed out 4C0/1, 4E0/1 and 4F0/1. Are these used internally by the USB or are they available for use? In the XMOS 208 porting hardware app note it shows using 4E0, 4E1 for I2C.

Thanks,

Hi Gordon!

You need this spreadsheet:

Thanks, why not just put this info in the data sheet? It shows the exposed pins for each part and would make it really easy to navigate a design.
