Freescale Semiconductor MMDS0508 4.10.3 Collecting Data

MMDS Target Component

4.10 Bus Analyzer

4–46 MMDS0508 Target Interface

4.10.3 Collecting Data

When your have initialized the emulator and the bus analyzer have been initialized,

and when you have connected any logic clips that you defined, emulation can begin.

4.10.3.1 Arming the Analyzer

Before you can start data collection, you must arm the bus analyzer. To do so, choose

the MMDS0508>Bus Trace>Arm Analyzer menu selection. The status bar shows

Armed status for the bus state analyzer, and the menu selection changes to Disarm

Analyzer.

4.10.3.2 Disarming the Analyzer

To stop the analyzer, choose the MMDS0508>Bus Trace>Disarm Analyzer menu

selection. The status bar shows Disarmed status for the bus state analyzer, and the

menu selection changes to Arm Analyzer.

4.10.3.3 Start Emulation

To begin emulation, choose the debugger Run>Continue menu selection, or enter any

other command that starts program execution. Emulation continues until a breakpoint,

a watchpoint, the bus analyzer, or you stop the emulation. When emulation stops, the

system updates data in the Bus Analyzer window (see below).

4.10.3.4 Status Bar

The debugger status bar shows the status of the bus analyzer. Before you arm the

analyzer, the status is Disarmed: not ready to collect data. After you arm the analyzer,

the status is Armed: ready to collect data. When emulation begins, the status is

Running: the analyzer is monitoring events. When the analyzer collects data, the status

is Analyzing.

4.10.3.5 Halt Data Collection

To halt data collection manually, choose the MMDS0508>Bus Trace>Disarm

Analyzer menu selection. This stops data collection, but does not stop emulation.

4.10.3.6 Halt Emulation

Stopping emulation also stops data collection, but leaves the analyzer armed. Data

collection resumes when emulation starts again.
