Does anyone know if there is an easy way to get a clock output from a UC3B? I'm trying to save space in my design by sharing a 16MHz crystal between the AVR32 and a nRF24L01+ radio. The nRF24L01+ will take a digital clock input from an external source, so all I need to do is find a way to get a 16MHz clock signal out of the UC3B.

Does anyone know if I can I take the signal off of XOUT? I couldn't find any documentation on that. Is a timer output a better solution? Presumably I'd have to run the AVR32 CPU and timer off of a PLL.

Hello,

yes it is and I know. Use a GClk output like shown in the EVK110x Driver Power manager examples.
No need for a timer output.
Do you mean with

or with

that you want to use the signal coming out of the XOUT?. I would think you can but if Atmel just run low signals on the crystal you can't. Therefore a data sheet approved way would be using one of the GClk outputs.

Those GCLK pins seem to be exactly what I want. Thanks! I seem to have missed them in my analysis of the data sheet.
