By selecting the terminal post trigger count, the user can control the
number of cycles that is stored. This can be used to speed uploading of
the BSA data if only a small portion of data is needed.
Note that the terminal count or post trigger cycles are valid only for
counted or sequential modes. For a counted mode, this field specifies
the number of cycles to be stored. For a sequential mode, this field
specifies the number of cycles to be stored after the trigger sequence
occurs.
An X in the stop-emulator field stops program execution when bus state
analyzer recording is done.
After selecting the mode, you can begin collecting data by pressing the
F7 (execute) key. This returns you to the debug screen.
Options explains how to continue from this point.

Description
buffer begins storing data from all cycles. This continues
through the occurrence of three events, A, B, and C, in
order, if event D does not occur. (If D occurs, the
sequencer starts again looking for event A.) Data storage
ends after the specified number of post-triggert cycles.
Otherwise, the bus state analyzer never can be triggered. If
you disable event D, you convert this mode to a simple,
three-event sequence.

C, then D. Otherwiser, the bus state analyzer never can be
triggered.
buffer begins storing data from N occurrences of cycles
that match the definitions of events A, B, C, or D
(whichever are enabled). Then the bus state analyzer
captures the next 4096 cycles.
