Button Functionality

PHASE_BUTTON Each time the button is pressed, the current INPx pattern becomes the pattern for INNx, the current

INNx pattern becomes the pattern for INPx.

PRF_BUTTON Changes the Pulse Repetition Frequency of the output waveform as given in Table 2 Each press

increases the PRF and then cycles back to 0.

CYCLE_BUTTON Changes the number of times the output pattern cycles within the pulse burst, as given in the Table 3.

Each press moves 1 level up and then back to 0

FREQ_BUTTON Changes the Frequency of the output waveform as given in the Table 4. Each press increases the

frequency and then cycles back to 0

RESET_BUTTON Reset all the setting to its default

PDM_BUTTON One press changes the mode to Power down mode.

CW_MODE_BUTTON First six times the button is pressed will change the pattern depth as shown in Table 5. Seventh press

will change the device to CW mode. In CW mode, pressing the button will revert back to 17-level. The

latch mode is unaffected. Refer to Table 5 and Table 6.

LATCH_MODE_BUTTON First press changes to latch mode. Every consecutive pulse will toggle the mode between Latch and

Non latch mode
