The board also uses the TRIG1 signal to initiate pretriggered data
acquisition operations. In most pretriggered applications, the TRIG1
signal is generated by a software trigger. Refer to the TRIG2 signal
description for a complete description of the use of TRIG1 and TRIG2
in a pretriggered data acquisition operation.
