6.18.1 EmbeddedICE
6.18.2 RealMonitor
Standard ARM EmbeddedICE logic provides on-chip debug support. The debugging of
the target system requires a host computer running the debugger software and an
EmbeddedICE protocol converter. The EmbeddedICE protocol converter converts the
remote debug protocol commands to the JTAG data needed to access the ARM core.
The ARM core has a debug communication channel function built-in. The debug
communication channel allows a program running on the target to communicate with the
host debugger or another separate host without stopping the program flow or even
entering the debug state. The debug communication channel is accessed as a
coprocessor 14 by the program running on the ARM7TDMI-S core. The debug
communication channel allows the JTAG port to be used for sending and receiving data
without affecting the normal program flow. The debug communication channel data and
control registers are mapped in to addresses in the EmbeddedICE logic. The JTAG clock
(TCK) must be slower than
RealMonitor is a configurable software module, developed by ARM Inc., which enables
real time debug. It is a lightweight debug monitor that runs in the background while users
debug their foreground application. It communicates with the host using the DCC, which is
present in the EmbeddedICE logic. The LPC2101/02/03 contain a specific configuration of
RealMonitor software programmed into the on-chip boot ROM memory.
