About EmbeddedICE Logic
The ARM7TDMI processor EmbeddedICE Logic provides integrated on-chip debug
support for the ARM7TDMI core.
The EmbeddedICE Logic is programmed serially using the ARM7TDMI processor
TAP controller. Figure 5-5 illustrates the relationship between the core, EmbeddedICE
Logic, and the TAP controller, showing only the pertinent signals.
