No
The default emulator configuration disables the
real-time mode. When the emulator is executing
the target program, you are allowed to enter
emulation commands that require access to target
system resources (display/modify: registers or
target system memory). If one of these commands
is entered, the system controller will temporarily
break emulator execution into the monitor.
Yes
If your target system program requires real-time
execution, you should enable the real-time mode in
order to prevent temporary breaks that might cause
target system problems.
Commands Not Allowed when Real-Time Mode is Enabled
When emulator execution is restricted to real-time and the emulator is
running user code, the system refuses all commands that require access
to processor registers or target system memory. The following
commands are not allowed when runs are restricted to real-time:
Register display/modification.
Target system memory display/modification.
Internal I/O registers display/modification.
If the real-time mode is enabled, these resources can only be displayed
or modified while running in the monitor.
Breaking out of Real-Time Execution
The only commands which are allowed to break real-time execution
are:
Processor, Reset
Processor, Go
Processor, Break
Processor, Step
