Hi!
I'd like to use an external 25MHz TCXO as a primary clock. Unfortunately, t he application notes (at least what I've found) are very laconic on this to pic. The only examples are of the OSCC module which is an internal oscillat or. According to the MachXO datasheet any pin can be used as a clock input but the preferred way is to connect external clock signals to the dedicated clock pins. It is clear that there are primary clock pins on the device an d I can feed the TCXO's output into one of them. But how can I refer to thi s primary clock in my Verilog code? It is also not clear how can I change t hat the primary clock input pins are clock pins and not the default I/O pin s...in the Spreadsheet tab, I couldn't find it.
Thank you in advance,
G
