    WORD MONITOR TRIGGER
    In the Word Monitor mode, there is a pattern recognition trigger and a pattern
    recognition interrupt. The 16-bit compare word for both the trigger and the interrupt
    is stored in the Monitor Trigger Word Register. The pattern recognition interrupt is
    enabled by setting the MT Pattern Trigger bit in the Interrupt Mask Register. The
    pattern recognition trigger is enabled by setting the Trigger Enable bit in
    Configuration Register #1 and selecting either the Start-on-trigger or the Stop-on-
    trigger bit in Configuration Register #1.
    The Word Monitor may also be started by means of a low-to-high transition on
    the EXT_TRIG input signal.
    SELECTIVE MESSAGE MONITOR MODE
    The PCI Enhanced Mini-ACE Selective Message Monitor provides monitoring of
    1553 messages with filtering based on RT address, T/R bit, and subaddress with
    no host processor intervention. By autonomously distinguishing between 1553
    command and status words, the Message Monitor determines when messages
    begin and end, and stores the messages into RAM, based on a programmable
    filter (RT address, T/R bit, and subaddress).
    The selective monitor may be configured as just a monitor, or as a combined
    RT/Monitor. In the combined RT/Monitor mode, the PCI Enhanced Mini-ACE
    functions as an RT for one RT address (including broadcast messages), and as a
    selective message monitor for the other 30 RT addresses. The PCI Enhanced
    Mini-ACE Message Monitor contains two stacks, a command stack and a data
