(4.0) USB-EA E
The USB-EA emulator allows non-intrusive debugging of the ADuC8xx series of devices.
The USB-EA Pod is shipped as part of the Quick Start Plus kits or, it may be purchased separately.
The following parts are supported by the USB-EA emulator:
Note, the ADuC812/814/816/824 are not supported.
The debugger interfaces to the ADuC8xx via a single pin – the EA pin of the ADuC8xx part. To
enter debug mode, the part must first be placed into download mode by toggling the Reset pin while
holding the Serial download pin low. When using the evaluation boards, this involves keeping the
Serial download button pressed while toggling the reset button.
