8.11. The debug communications channel

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

The communications 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 comms channel registers, the processor can access a 1-bit debug status register for use in the real-time debug configuration.
