Running the Sample Starter Project
A sample starter program provided on the ZDS II CD-ROM demonstrates how to write
proper code for the eZ80AcclaimPlus! Development Board. The starter program is written
so that it will default to the UART-to-USB Port P3 on the Board. The program writes a few
character strings either to this port, or to the simulated UART output window when running the Simulator Debug Tool (see the Viewing the Starter Project Output via the ZDS II
Instruction Set Simulator section on page 12). Before running the starter program, however, the eZ80AcclaimPlus! Development Board must be connected to your PC.
After you create your own application program, you can use ZDS II to download the code
you created into eZ80F91 memory for testing and debugging.
Procedure
Observe the following steps to build and run the sample starter program for viewing in a
terminal emulation program on your PC, such as HyperTerminal.
Note: While HyperTerminal is discussed in this document, it is not available on Windows 7 or
Vista machines. As an alternative, consider using Tera Term, which is available for download from the Internet.
1. If you haven’t already connected the UART-to-USB cable to the Board, return to the
Connecting the eZ80AcclaimPlus! Development Board to your PC section on page 8.
2. Launch HyperTerminal. From the File menu, click New Connection.
3. In the Name field, enter a name that describes the connection.
4. In the Icon box, select an appropriate icon for your connection, then click OK.
5. In the Connect To dialog box, and from the Connect using: drop-down menu,
choose the COM port that is connected to the UART-to-USB port on the
eZ80AcclaimPlus! Development Board.
6. In the Port Settings dialog box, set the following options:
– Bits per second: 57600
– Data bits: 8
– Parity: None

Viewing the Starter Project Output via the ZDS II Instruction Set
Simulator
The eZ80Acclaim! Cycle-Accurate Instruction Set Simulator interfaces with the ZDS II
Debugger to simulate the execution of programs without using an emulator or target hardware. The Instruction Set Simulator uses the command set of the Debugger to perform
tasks such as simulating timers and interrupts.
To use the eZ80Acclaim! Instruction Set Simulator as an option, observe the following
steps to view the output of the starter.zdsproj project in the ZDS II IDE.
1. In ZDS II, open the starter.zdsproj project.
2. From the Project menu in ZDS II, choose Settings to open the Project Settings dialog
box. Click the Debugger tab.
3. In the Debugger dialog, select eZ80F91ModDevKit_RAM from the Target pane by
clicking the checkbox next to the specific target name. Next, select Simulator from
the Debug Tool drop-down menu.
4. Click OK to close the Project Settings dialog box.
5. If you are prompted to rebuild any affected files, click Yes. Otherwise, choose Build
from the menu bar, then click Rebuild All.
6. When the build is complete, explore the Debug toolbar’s many debugger features. To
connect to the Simulator, choose Reset from the Debug menu.
7. Next, open the Simulated UART Output window to view the output of the program by
navigation via the View menu to Debug Windows → Simulated UART Output.
8. To run the application, select Go from the Debug menu. Until the default settings are
changed, the following output will be presented in the HyperTerminal window:

Note: Schematic diagrams for the eZ80AcclaimPlus! Development Board are provided in the
Schematic Diagrams chapter on page 18.
The eZ80AcclaimPlus! Development Board is driven by the eZ80F91 MCU with an external 50 MHz (Y1) crystal and an on-chip PLL programmed to run on the eZ80F91 MCU at
its internal frequency of 50 MHz. The chip employs an Ethernet Media Access Controller
(EMAC) with a Media-Independent Interface (MII) that allows the eZ80F91 MCU to it to
interface to all available industry-standard PHYs.
For this eZ80AcclaimPlus! implementation, the ICS1894-40 (U5) was selected to provide
a suitable price/performance solution.
Debug connector (J1) provides access to the eZ80F91 MCU so that the user can download
and control the execution of the sample projects provided with the Kit or his/her own project(s) using the USB Smart Cable included in the Kit.

Memory
The eZ80AcclaimPlus! Development Board features the following memory configurations:
•
•
•
•
8 KB on-chip SRAM
256 KB on-chip Flash
1 MB off-chip SRAM; U2 and U3 are accessible by chip selects CS1 and CS2
8 MB off-chip Flash: U11 is accessible by chip select CS0
To learn more about the operation of the eZ80F91 MCU’s internal memory, refer to the
eZ80F91 ASSP Product Specification (PS0270).
1. The Board features two power source options. It can be powered by connecting Port
P3 (USB Mini-B) to the USB port of the development PC using the USB A to USB
mini-B cable included in the Kit. The other option is to connect a female plug to an
external 5 VDC source with at least 300–400mA of current to Port P2. A drawing of
an optional external power supply plug is shown in Figure 8.
Legend
A = 3.5 mm
B = 1.3 mm
C = 6 mm or longer
Figure 8. Female Plug
When the Board is powered via a USB connection, communication with the development
PC can be established through the FT232RL chip (U8) to provide a USB-to-serial interface. The UART0 block of the eZ80F91 MCU is connected to this chip.
An on-board USB port (U6) provides overcurrent protection in the event of a short or if a
device is connected to the Board that requires more than 500 mA @3.3 V. If either condition occurs, LED2 will illuminate.

If the Board is powered via a wall outlet and P3 is not used, communication with the PC
can be established through a DB9 female connector (P4) which is connected to the
UART1 block of the eZ80F91 MCU.
All signals that control access to on-board memory are routed to the Board’s test points;
please refer to Appendix B. Schematic Diagrams on page 18.
Jumper Settings
All available GPIO ports that exist on the eZ80F91 MCU are routed to connector J10,
which is a standard 0.1"-pitch header. These signals are only routed to the odd-numbered
pins; all even-numbered pins are connected to GND. Please refer to Appendix B. Schematic Diagrams on page 18 for the exact signal connections to J10. The remaining jumpers are described in Table 2.
