Reference Clock Out

Probably dumb question, but I'm looking to use the Reference Clock Out on a dsPIC33CK256MP208 to drive the clock in on a peripheral. I'm not finding information in the CCS C manual. Am I missing it, or do I need to use asm to implement it?

Thanks,

While don't use the PIC, but I'd look in the device.H 'header' file to see what CCS has done.
It might be a simple 'set bit to enable ' ??

Just ensure that you don't have the slew rate control enabled for that particular pin. If the processor comes with that ability, the default is for it to be on/enabled.

Learned that the hard way some time ago when I also tried to enable the reference clock out.
