3�7�2 SSI_TRIG
As an output, the SSI_TRIG signal reflects the trigger event signal in an acquisition
sequence. As an input, the PCIe-69814 accepts the SSI_TRIG signal to be the trigger event
source. The signal is configured in the rising edge-detection mode.
3�8 SDI
In some applications, marks may need to be added to some data. The PCIe-69814 uses SDI
to accomplish this. The lowest 3 LSBs correspond to the logic level of SDI2 to SDI0.
