Table 5.3—PXIe Trigger to Protocol Sync Mapping
Triggers are mutually exclusive; however, syncs are not. For example, only
PXI_TRIG[0] or PXIe_DSTARA can be configured at one time to trigger the
protocol logic; however, the protocol logic can drive the sync out to both
PXI_TRIG[2] and PXI_STAR at the same time.
