Using a Structured Timing Interrupt (STI) with auto-tuning
Although a PID instruction works if it is not controlled by a Structured Timing
Interrupt (STI), using an STI increases the auto-tune success rate because the
auto-tune will operate on a fixed cycle.

The following example program is shows the variables used to configure the
parameters for auto-tuning.
