MMDS Target Componen t
4.10 Bus Analyzer
4–42 MMDS0508 Target Interface
In triggered modes, the analyzer uses your term definitions to track the occurrence of
events, then stop data collection according to some combination of the events. Each
term has an associated Pre Event count that counts events for that term. The sequencer
condition includes that term, once the count reaches the pre-event count.
An event is a pattern of bus signals (which can include address and data values) that
logic clips and miscellaneous MCU signals connect to the analyzer. Alternatively, an
event can be the negation of a defined pattern. You can define each signal to be
asserted, negated, or ignored (don't care).

4.10.2.4 Non-Triggered Modes
In non-triggered modes, data collection continues until you stop the analyzer.
4.10.2.4.1 Continuous: All Cycles
Provides a real-time, non-invasive trace of MCU bus activities. The bus analyzer
stores all cycles, continuously recording bus data in the trace buffer during any
emulation of the user target system. This mode does not let you define qualifications
for triggering or halting data collection.
