The ARM1136JF-S debug unit assists in debugging software running on the ARM1136JF-S processor. You can use an ARM1136JF-S debug unit, in combination with a software debugger program, to debug:
ARM processor based hardware systems.
The debug unit enables you to:
stop program execution
examine and alter processor and coprocessor state
examine and alter memory and input/output peripheral state
restart the processor.
The DBGEN signal enables the debug unit.
The following sections describe the ways you can debug the ARM1136 processor:
The ARM1136JF-S debug interface is based on the IEEE Standard Test Access Port and Boundary-Scan Architecture.
