At high pulse rates, duty cycle is 50%. At rates less than 1/(2*PWmax), the negative going pulse width is PWmax. The
allowed range is 0 to 2
31-1.
The pulse width for the PULSE3 and PULSE4 outputs is always at a 50% duty cycle.
The initial voltage level of the pulse pins is defined with the PULSE_INIT pin.
