Evaluation Kit User Guide
USB-EA EMULATOR FOR DEBUGGING
The USB-EA emulator allows nonintrusive debugging of the
ADuC8xx series of devices. The USB-EA pod is either shipped
as part of the Quick Start Plus kits or purchased separately.
The following parts are supported by the USB-EA emulator:
•
•
•
•
•
•
•
•
•
Note that the ADuC812/ADuC814/ADuC816/ADuC824 are
not supported by the USB-EA emulator.
The debugger interfaces to the ADuC8xx via a single pin—the
EA pin of the ADuC8xx part. To enter debug mode, first place
the part into download mode by toggling the RESET pin while
holding the serial download pin low. When using the evalu-
ation boards, this involves keeping the Serial Download button
pressed while toggling the Reset button.
CONNECTING THE USB-EA EMULATOR TO THE
TARGET BOARD
The pod connects to a PC via a standard mini-USB cable. It
connects to a target board via a 2-pin header.
DRIVERS FOR THE USB-EA EMULATOR
If the USB drivers for the USB-EA dongle do not install
automatically on your PC, then download drivers for the
FT245R part for your operating system from the official website
for the Future Technology Devices International Ltd.

When the drivers are installed and the USB-EA dongle is
connected to the PC, it appears as an extra COM port under
the Device Manager window as shown in Figure 7.
The older versions of the Keil tools only work with COM ports
numbered COM8 or lower. If your PC allocates a COM port
number of COM9 or higher, change the COM port number to
a lower number by completing the following steps:
1.
2.
Right-click your mouse on the USB Serial Port entry in
the Device Manager window and then select Properties.
Next, select the Port Settings tab and click Advanced.
