Trigger message #1 here:
Format: 0 = Disabled
1 = Enabled. Trigger message
(In Bit Trigger Mode, each bit of each word of the Block Transfer Write corresponds
to a message number to be triggered. Messages 1–465 can be triggered in this way.
The Bit Field Distributor “turns on” the messages by setting the bit
corresponding to a message number in the Block Transfer Write table.
