27. Debug Unit (DBGU)
27.1
27.2
6221I–ATARM–17-Jul-09
Description
Embedded Characteristics
The Debug Unit provides a single entry point from the processor for access to all the debug
capabilities of Atmel’s ARM-based systems.
The Debug Unit features a two-pin UART that can be used for several debug and trace purposes
and offers an ideal medium for in-situ programming solutions and debug monitor communica-
tions. The Debug Unit two-pin UART can be used standalone for general purpose serial
communication.
Moreover, the association with two peripheral data controller channels permits packet handling
for these tasks with processor time reduced to a minimum.
The Debug Unit also makes the Debug Communication Channel (DCC) signals provided by the
In-circuit Emulator of the ARM processor visible to the software. These signals indicate the sta-
tus of the DCC read and write registers and generate an interrupt to the ARM processor, making
possible the handling of the DCC under interrupt control.
Chip Identifier registers permit recognition of the device and its revision. These registers inform
as to the sizes and types of the on-chip memories, as well as the set of embedded peripherals.
Finally, the Debug Unit features a Force NTRST capability that enables the software to decide
whether to prevent access to the system via the In-circuit Emulator. This permits protection of
the code, stored in ROM.
• Composed of two functions:
• Two-pin UART
• Debug Communication Channel Support
– Two-pin UART
– Debug Communication Channel (DCC) support
– Implemented features are 100% compatible with the standard Atmel
– Independent receiver and transmitter with a common programmable Baud Rate
– Even, Odd, Mark or Space Parity Generation
– Parity, Framing and Overrun Error Detection
– Automatic Echo, Local Loopback and Remote Loopback Channel Modes
– Support for two PDC channels with connection to receiver and transmitter
– Offers visibility of and interrupt trigger from COMMRX and COMMTX signals from
