-/**
- * The PWM module is only used to generate interrupts at specified times. It
- * is NOT used to directly toggle pins. The ISR writes to the pin assigned to
- * that interrupt.
- *
- * All PWMs use the same repetition rate.  The G2 needs about 10KHz min in order to
- * not have obvious ripple on the Vref signals.
- *
- * 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.

+ * not have obvious ripple on the Vref signals.
+ *
+ * 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.
