The pin PULSE_INIT determines the logic level applied to the pulse pins on power-up, i.e. with PULSE_INIT low, the pulse
pins will be initialized to low (default = 1).
The pulse width PW is controlled with the PULSEWIDTH register for the PULSER and PULSEW output pins per the following
formula:

The PULSE3 and PULSE4 output pins will always generate pulses with 50% duty cycle.
