ARM DDI 0029G
Debug target
The ARM7TDMI processor has hardware extensions that ease debugging at the lowest
level. The debug extensions:
•
•
•
•
The major blocks of the debug target are shown in Figure 5-2.
The ARM CPU core
The EmbeddedICE Logic
The TAP controller
allow you to halt program execution
examine and modify the core internal state of the core
view and modify the state of the memory system
resume program execution.

EmbeddedICE
This has hardware support for debug.
This is a set of registers and comparators used to generate debug
exceptions such as breakpoints. This unit is described in About
EmbeddedICE Logic on page 5-13.
This controls the action of the scan chains using a JTAG serial interface.
