/*! \file driver_pit.h
    \brief Provides a simple abstraction for a periodic interval timer.

   Bare metal implementations of the sensor fusion library require at least
   one periodic interrupt for use as a timebase for sensor fusion functions.
   The Periodic Interval Timer (PIT) is one such module that is commonly
   found on NXP Kinetis MCUs.  The PIT functions are only referenced at the
   main() level.  There is no interaction within the fusion routines themselves.
