+ * The data structures are setup to minimize the computation done by the ISR which
+ * minimizes ISR execution time.  Execution times are 0.8 to 1.1 microseconds.

+ * FIve PWM interrupt sources are used.  Channel 0 sets the base period.  All Vref
+ * signals are set active when this counter overflows and resets to zero.  The compare
+ * values in channels 1-4 are set to give the desired duty cycle for that Vref pin.
+ * When counter 0 matches the compare value then that channel generates an interrupt.
+ * The ISR checks the source of the interrupt and sets the corresponding pin inactive.
+ *
+ * Some jitter in the Vref signal is OK so the interrupt priority is left at its default value.
