9.10. The debug communication channel

The ARM9E-S EmbeddedICE-RT logic contains a communication channel for passing information between the target and the host debugger. This is implemented as coprocessor 14.

The communication channel comprises:

These registers are located in fixed locations in the EmbeddedICE-RT logic register map and are accessed from the processor using MCR and MRC instructions to coprocessor 14.

In addition to the communication channel registers, the processor can access one bit of the 32-bit debug status register for use in the real-time debug configuration.
