Configuring the Emulator

When Modifying the Microprocessor Clock Source

When Modifying the Microprocessor Clock Source
In normal mode, if you are using the emulator in ACT mode, you must use an
external target system clock. The external target system clock must be an
oscillator unless you are using the emulator in ACT mode, in which case the
external target system clock may be a crystal.
Information about plugging the emulator into a target system is included in
the 6833x Installation/Service/Terminal Interface Guide.

When Restricting the Emulator to Real-time Runs

If your target system circuitry is dependent on constant execution of
C A U T I O N
program code, you should restrict the emulator to real-time runs. This will
help insure that target system damage does not occur. However, remember
you can still execute the reset, break, and step commands; you should use
caution in executing these commands.
The default configuration does not restrict the emulator to real-time runs.
Therefore, the emulator might make temporary breaks into the monitor to
complete certain commands. However, you may wish to restrict runs to
real-time to prevent temporary breaks that might cause target system
problems.
When runs are restricted to real-time and the emulator is running the user
program, all commands that cause a break (except reset, break, run, and
step are refused.
