I am trying to reduce the ppm number on the 5LP. I have enabled the USB tab in the clock settings and have got a clock running at 1250ppm. I was hoping to attach an external crystal with some capacitors and use them to create a more accurate clock.
I was hoping to use a watch crystal with 20ppm. This is desirable as I am looking to microsecond timers that would be accurate.
Can I use the watch crystal, create and use a clock based off this at 24Mhz?
I am trying to locate documentation on this and my searches do not amount to any thing.
