Hi Team,
. I want to use the on board XTAL, and hence the Secondary input into the PLL. I configured all the internals with the GUI to do this and all looked good, but when programmed I got no output at all.
I had the REFSEL input set to Vim, as shown in the table below, but to get the module to work to my settings I had to change the REFSEL to be pulled high. Please could you provide a little insight into this as our proto is currently going to have the Vim setting – should we change the BoM to make it pulled up?
