Figure 4-19: Infinite Iterative Waveform Generation with Post-trigger and
DLY2_Counter = 0
NOTES When running infinite iterative waveform generation, set-
ting IC_Counter is ineffective to the waveform genera-
tion. It only makes a difference when setting Stop mode
III. Refer to Figure 4-22.
Setting finite and infinite iterative waveform generation is
not discussed in this manual. Refer to software documen-
tation for related information.
Delay2 in Repetitive Waveform Generation
To diversify the D/A waveform generation, we add a DLY2
Counter to separate two consecutive waveforms in repetitive
waveform generation. The time between two waveforms is set
by the value of DLY2 Counter. The Delay2 counter starts to
count down after a waveform generation 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 units of TIMEBASE (delay
time = DLY2_Counter/TIMEBASE) or in units of update period
(delay time = DLY2_Counter * UI_counter/TIMEBASE), so the
delay time can reach a wider range.
