Register	Field	Bits	Function	device
PhaseIncrement	*	31:0	Set frequency of generated sinewave	/dev/pio_phaseIncrement
Pulse1On	*	31:0	Duration of first pulse	/dev/pio_pulse1On
Pulse1Off	*	31:0	Interval between first and second pulses	/dev/pio_pulse1Off
Pulse2On	*	31:0	Duration of second pulse	/dev/pio_pulse2On
Pulse2Off	*	31:0	Minimum interval between end of second pulse and first pulse repeat	/dev/pio_pulse2off
PulseControl	*			/dev/pio_pulseControl
	Digitizer Reset	6	0 = normal operation; 1 = reset digitizer
	ADC Test mode	5:4	00 = adc input (normal operation); 01 = adc test signal (count); 10 = test mode (DAC output); 11 = test mode (constant 0xDEADBEEF)
	ADC gate enable	3	0 = normal operation; 1 = disable ADC gate;
	DAC B output	2	0 = carrier; 1 = trigger
