Detailed Description

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.
