AT91RM3400 Debug and Test Features
Overview
1790A–ATARM–11/03
The AT91RM3400 features a number of complementary debug and test capabilities. A
common JTAG/ICE (In-circuit Emulator) port is used for standard debugging functions,
such as downloading code and single-stepping through programs. The Debug Unit pro-
vides a two-pin UART that can be used to upload an application into internal SRAM. It
manages the interrupt handling of the internal COMMTX and COMMRX signals that
trace the activity of the Debug Communication Channel.
A set of dedicated debug and test input/output pins give direct access to these capabili-
ties from a PC-based test environment.
