4.10.2.6.3 Sequential: A + B -> C + D
Select this option to start bus-analyser recording when either of two sequences occurs:
(1) event A, followed by either event C or event D, or (2) event B, followed by either
event C or event D. Data storage ends after the specified number of post-trigger
cycles. You can simplify this sequence by leaving an event undefined.
4.10.2.6.4 Sequential: A -> B -> C-> D
Select this option to start bus-analyser recording as soon as events A, B, C, and D
occur, in that order. Data storage ends after the specified number of post-trigger
cycles.
4.10.2.6.5 Nth Event After A+B+C+D
Select this option to start bus-analyser storage of data that matches events A, B, C, and
D, until the analyzer stores the Nth event. Then, the analyzer stores as well the next
4096 cycles. The maximum N value is 4096, so this mode lets you store as many as
4096 events, followed by 4096 cycles.
4.10.2.7 Counted/Sequential Recording Mode
This paragraph explains how to switch beetween Counted and Sequential Recording
Mode.
4.10.2.7.1 Terminal Count/Post Trigger Cycles (1..8191)
For a counted mode, this edit box specifies the number of bus cycles that the analyzer
traces. For a sequential mode, this edit box specifies the number of post-trigger cycles
that the analyzer traces. The value range for this edit box is 1 through 8191. (For a
continuous modes, the analyzer ignores this value.)
4.10.2.7.2 Stop the emulator when recording completes
Check this checkbox to stop emulation as soon as the analyzer stops tracing bus
cycles. If this checkbox is clear, emulation continues, even after analyzer data storage
ends.
NOTE The terminal count/post trigger cycles value applies only to counted
or sequential modes. For a counted mode, it is the number of cycles
the analyzer stores. For a sequential mode, it is the number of cycles
the analyzer stores after the trigger sequence occurs.
