Configure the Hardware
Configuring the Z8 Encore! XP®F64xx Series ICE consists of selecting
emulator jumper options and setting up Ethernet communications
between the emulator and your PC.
Setting Jumpers on the Z8 Encore! XP®F64xx Series ICE
There is one jumper on the Z8 Encore! XP®F64xx Series ICE. Jumper
J12 allows you to select whether the emulator Watch-Dog Timer uses the
32-kHz internal oscillator or is programmable using the settings in ZDS
II.
Setting Up Ethernet Communications
The default IP address and subnet mask of the Z8 Encore! XP®F64xx
Series ICE are 192.168.1.50 and 255.255.255.0, respectively. To enable
communication between the PC running ZDSII and the Z8 Encore! XP®

F64xx Series ICE, you must either change the PC’s Ethernet settings to
match those of the Z8 Encore! XP®F64xx Series ICE or vice versa.
If using the PC in a stand-alone configuration, set the PC’s IP address to
192.168.1.21 and its subnet mask to 255.255.255.0. See “Changing the
PC’s Settings to Match the Z8 Encore! XP® F64xx Series ICE” on
page 7.
If working in a networked environment, set the Z8 Encore! XP®F64xx
Series ICE IP address and subnet mask to match the existing network
setup. See “Changing Z8 Encore! XP® F64xx Series ICE Settings to
Match the PC” on page 12.

8. Use the I command to change the Z8 Encore! XP®F64xx Series ICE
IP address to one that is compatible with the PC. Use caution to avoid
creating a conflicting IP address.
9. Use the S command to change the Z8 Encore! XP®F64xx Series ICE
subnet mask to one that is compatible with the PC. Typically, the sub-
net mask is the same as that of the PC.
10. Use the G command to change the Z8 Encore! XP®F64xx Series ICE
Gateway to one that is compatible with the PC. Typically, the gateway
is the same as that of the PC.
11. Use the C command to verify the new settings.
12. Exit HyperTerminal.
13. Cycle the power on the Z8 Encore! XP®F64xx Series ICE for the
new settings to take effect.
The hardware is now configured and ready for application development.
Running a Sample Project
After installing the ZDS II software and setting up the hardware, you can
run a sample software project to verify proper emulator operation and
experiment with the trace and event system. The sample project ice-
demo.pro is included in the ZDS II sample directory, located in:
c:\Program Files\ZiLOG\ZDSII_<product>_<version>
\samples\<processor type>_<demo name>
Start ZDS II for the Z8 Encore! XP®F64xx Series ICE and follow the
instructions below to run icedemo.pro.

The following procedures require that the emulator be connected
to a target board, such as the Z8 Encore! F64xx Series Develop-
ment Board.
1. Select File --> Open Project--> c:\Program
Files\ZDSII_Z8Encore!_F642X_Emulator_4.6.x\sam-
ples\FZ8F642x_ICEDemo\src
\icedemo.pro.
2. Double-click main.c in the Project Files window.
3. Open Project --> Settings.
4. In the General tab, verify the CPU field is set to Z8F6423.
5. In the Debugger: Select Z8 Encore! Emulator and then click the Con-
figure Driver button.
6. The Encore! Emulator dialog box appears. The IP Address field dis-
plays a default IP address, 192.168.1.50. Enter the Z8 Encore! XP®
F64xx Series ICE IP address you configured during hardware install.
Leave the other settings as they are.
7. Select the Target VCC voltage. If the emulator is connected to the Z8
Encore! XP F64xx Series development board, select 3.0V. If running
the emulator in standalone mode, select Standalone. If the emulator is
connected to a custom target, select the voltage appropriate for that
target.
The emulator’s voltage comparator is designed as a target power
sensor, not as a precision voltage measurement device. If you set
the Target VCC to match your target and the target’s voltage drifts
downward, the power sensor may no longer detect it. The emula-
tor may therefore not connect to the target. In such cases, set the
Target VCC voltage progressively lower until you get a good con-
nection.

8. Select the appropriate clock frequency or enter the clock frequency in
the Other field. This should match the 20-MHz Clock Oscillator on
Y4 of the emulator.
The emulator clock cannot be supplied from the Target application
Board.
9. Click OK to close the Z8 Encore! Emulator dialog box.
10. Click OK to close the Project Settings dialog box.
11. Open the Trace window by selecting View --> Debug Windows -->
Trace.
12. Make sure that the Event System is disabled (The Edit --> Event Sys-
tem command does not have a check mark to the left of the com-
mand).
13. In the Trace window, click the Clear Trace button.
14. Build the project now by selecting Build --> Build, or by pressing F7.
The following steps describe two ways to use the trace and event
system. For details on running the trace and event system, refer to
the ZDS II online help and the ZDS II—Z8 Encore! User Manual,
located in the docs directory of the ZDS II CD-ROM.
Running a Simple Trace
Now we’ll run a simple trace by starting the program, then stopping it and
viewing the trace buffer. Click the Go button in the toolbar. ZDS II com-
municates with the emulator, then runs the demo program. When the trace
buffer is full, the “CPU breaks on Trace-Buffer Full” message displays in
the Debug window. Click Get Frames to display the trace information.
View the trace window and you’ll see that all program cycles are logged.
Click the Options button in the Trace window to select the way in which
you’d like the trace displayed.

Using Events to Start and Stop a Trace
1. Now we’ll define a pair of events to automatically start and stop a
trace. Use this feature, for example, to trace execution of a particular
module in your program and see the context in which the module is
running with respect to other program modules.
2. Select Tools --> Trace and Event System. Click the Enable event sys-
tem check box, and click the Break when trace buffer is full check
box.
3. Select Event 0. We’ll use this as the event to trigger a trace.
4. In the When: section, click the Program counter check box and set the
Program Counter to 03F2 and the Mask to FFFF.
5. In the Then: section, click the Trace check box and select the On
radio button.
6. Select Event 1. We’ll use this as the event to break the trace.
7. In the When: section, click the Program counter check box and set the
Program Counter to 041D and the Mask to FFFF.
8. In the Then: section, click the Trace check box. Select the Off radio
button, and select the AND BREAK radio button. Click the OK but-
ton.
9. In the Trace window, click the Clear Trace button.
10. Reset the Debugger by clicking the Reset button in the toolbar, or by
selecting Build --> Debug --> Reset.
11. Run the Debugger by clicking the Go button or by selecting Build -->
Debug --> Go.
12. Wait for the program execution to break.
