9.16. Debug communications channel

The ARM9TDMI EmbeddedICE macrocell contains a communication channel for passing information between the target and the host debugger. This is implemented as coprocessor 14.

The communications channel consists of:

These registers are in fixed locations in the EmbeddedICE register map, as shown in Figure 9.11. You can access the registers from the processor using MCR and MRC instructions to coprocessor 14.
