Delay2 in Iterative Waveform Generation
To stretch out the flexibility of the D/A waveform generation, we
add a DLY2_Counter to separate two consecutive waveforms
in iterative waveform generation. The time between two wave-
forms is assigned by setting the value of the DLY2_Counter.
The DLY2_Counter starts to count down after a waveform gen-
eration finishes and the next waveform generation starts right
after it counts down to zero, as shown in Figure 4-20. This
DLY2_Counter is 16-bit wide and you may set the delay time in
unit of TIMEBASE (delay time = DLY2_Counter/TIMEBASE) or
in unit of update period (delay time = DLY2_Counter *
UI_Counter/TIMEBASE), so the delay time can reach a wider
range.
