Please see: https://github.com/mossmann/hackrf/issues/85

This is a firmware enhancement we would like to have.  The best way to
implement PPS input would probably be by using a timer on the LPC4320.

I don't think the CPLD would be useful for this.  A timer on the LPC4320
would run in parallel to the CPU.
