About EmbeddedICE-RT
The ARM9E-S EmbeddedICE-RT logic provides integrated on-chip debug support for
the ARM9E-S core.
EmbeddedICE-RT is programmed serially using the ARM9E-S TAP controller.
Figure 7-3 shows the relationship between the core, EmbeddedICE-RT, and the TAP
controller. It only shows the signals that are pertinent to EmbeddedICE-RT.
The EmbeddedICE-RT logic comprises:
•
•
•
The debug control register and the debug status register provide overall control of
EmbeddedICE-RT operation.
two real-time watchpoint units
two independent registers, the debug control register and the debug status register
debug comms channel.
