HD6475368CP Datasheet, PDF (47/108 Pages) Agilent(Hewlett-Packard) – H8/536 Emulator PC Interface

Using the Analyzer
The H8/536 emulation analyzer has 48 trace signals which monitor
internal emulation lines (address, data, and status lines). Optionally,
you may have an additional 16 trace signals which monitor external
input lines. The analyzer collects data at each pulse of a clock signal,
and saves the data (a trace state) if it meets a "storage qualification"
condition.
Note
Emulators which have the optional external analyzer will display the
Interna/External options after the commands in the following
examples. Enter Internal to execute the examples.
Resetting the
Analysis
Specification
To be sure that the analyzer is in its default or power-up state, select:

Specifying a Simple
Trigger
Suppose you wish to trace the states of the sample program which
follow the read of a "B" (42 hex) command from the command input
byte. To do this, you must modify the default analysis specification by
selecting:
Analysis, Trace, Modify
The emulation analysis specification is shown. Use the right arrow key
to move the cursor to the "Trigger on" field. Type "a" and press Enter.
You’ll enter the pattern expression menu. Press the up arrow key until
the addr field directly opposite the pattern a= is highlighted. Type the
address of the command input byte, using either the global symbol
Cmd_Input or address 0fc00, and press Enter.
The "Data" field is now highlighted. Type 42xx and press Enter. 42 is
the value of the "B" command and the "x"s specify "don’t care" values.
