The Trace Window
The Trace window displays trace results and shows source code lines that
correspond to the execution captured by the analyzer. Optionally, bus cycle
states can be displayed along with the source code lines.
The Trace window has control menu commands that let you display bus
cycles, specify whether count information should be absolute or relative, or
copy information from the window.
The Trace window opens automatically when a trace is complete.
For each line in the Trace window, the trace buffer state number, the type of
state, the module name and source file line number, the function name, the
source line, and the time count information are displayed.
The << and >> buttons let you move between the multiple frames of trace
data that are available with newer analyzers for the HP 64700.
The type of state can be a sequence level branch (SEQ), a state that satisfies
the prestore condition (PRE), or a normal state that matches the store
conditions (in which case the type field is empty).
Bus cycle states show the address and data values that have been captured
as well as the disassembled instruction or status mnemonics.
On startup, the system defaults to the source only display mode, where only
source code lines are displayed. The source/bus cycle mixed display mode
