ARM7TDMI
The AT91CAP7E 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 down-
loading code and single-stepping through programs. The Debug Unit provides 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 Communica-
tion Channel.
A set of dedicated debug and test input/output pins gives direct access to these capabilities from
a PC-based test environment.
