Control registers
Register | Bits | Function | device |
---|---|---|---|
PhaseIncrement | 31:0 | Frequency of generated sinewave | /dev/pio_phaseIncrement |
Pulse1On | 31:0 | Length of first pulse | /dev/pio_pulse1On |
Pulse1Off | 31:0 | Interval between first and second pulse | |
Pulse2On | 31:0 | Length of second pulse | /dev/pio_pulse1Off |
Pulse2On | 31:0 | Interval between second pulse and end of cycle | /dev/pio_pulse2Off |
PulseControl | /dev/pio_pulse2On | ||
ADC DMA source | 4 | 0=normal operation (ADC data); 1=A/D test (count) |
