 *  Fast PWMS
 *
 *  The LPC1768's hardware PWM controller has 6 channels.  Each channel
 *  can be setup to either control a dedicated pin directly or to generate
 *  an interrupt.  The direct method's duty cycle is accurate to within a
 *  a microsecond.  The interrupt method's average duty cycle has the
 *  the same accuracy but the individual cycles can vary because of higher
 *  priority interrupts.
 *
 *  All Fast PWMs have a 50Hz rate.
 *
 *  The following pins/signals use the direct method.  All other pins use the
 *  the interrupt method. Note that SERVO2_PIN and RAMPS_D8_PIN use the
