Using the Trigger
Control Register
To set up the Trigger Control Register for the VXIbus trigger types:
SYNC mode: This mode allows the card to receive a trigger from one of
the VXI backplane TTL trigger lines. To set the VXIbus SYNC trigger
mode, the Trigger Mode field is set to SYNC (00) and the Trigger Source
field is set to one of the *TTLTRIG lines. The Trigger Out field is not used.
OUTPUT mode: This mode allows the card to receive a trigger from one
TTL trigger line and also source a trigger on another TTL trigger line. The
output mode is not a VXIbus defined trigger mode. The output mode is
used to synchronize additional modules. The Trigger Mode field is set to
OUTPUT (11), the Trigger Source field is set one of the *TTLTRIG lines,
and the Trigger Out field is set to a different *TTLTRIG line.
