Delay Trigger Acquisition
Use delay trigger acquisition in applications where you want to
delay the data collection after the occurrence of a specified trig-
ger event. The delay time is controlled by the value, which is
pre-loaded in the Delay_counter (16bit). The counter counts
down on the rising edge of the Delay_counter clock source
after the trigger condition is met. The clock source can be soft-
ware programmed either by the TIMEBASE clock (40MHz) or
A/D sampling clock (TIMEBASE / SI_counter). When the count
reaches 0, the counter stops and the card starts to acquire
