LPC2290
16/32-bit ARM microcontroller with external memory interface
6.19 Emulation and debugging
The LPC2290 support emulation and debugging via a JTAG serial port. A trace port
allows tracing program execution. Debugging and trace functions are multiplexed only with
GPIOs on Port 1. This means that all communication, timer and interface peripherals
residing on Port 0 are available during the development and debugging phase as they are
when the application is run in the embedded system itself.
6.19.1 EmbeddedICE
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 convertor. EmbeddedICE protocol convertor 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.
6.19.2 Embedded trace
Since the LPC2290 has significant amounts of on-chip memory, it is not possible to
determine how the processor core is operating simply by observing the external pins. The
Embedded Trace Macrocell (ETM) provides real-time trace capability for deeply
embedded processor cores. It outputs information about processor execution to the trace
port.
The ETM is connected directly to the ARM core and not to the main AMBA system bus. It
compresses the trace information and exports it through a narrow trace port. An external
trace port analyzer must capture the trace information under software debugger control.
Instruction trace (or PC trace) shows the flow of execution of the processor and provides a
list of all the instructions that were executed. Instruction trace is significantly compressed
by only broadcasting branch addresses as well as a set of status signals that indicate the
pipeline status on a cycle by cycle basis. Trace information generation can be controlled
by selecting the trigger resource. Trigger resources include address comparators,
counters and sequencers. Since trace information is compressed the software debugger
requires a static image of the code being executed. Self-modifying code can not be traced
because of this restriction.
6.19.3 RealMonitor
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 (Debug
Communications Channel), which is present in the EmbeddedICE logic. The LPC2290
contain a specific configuration of RealMonitor software programmed into the on-chip
flash memory.

7. Limiting values
[1] The following applies to Table 5:
a) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless
otherwise noted.
[2] Including voltage on outputs in 3-state mode.
[3] Only valid when the V
DD(3V3)
supply voltage is present.
[4] Not to exceed 4.6 V.
[5] The peak current is limited to 25 times the corresponding maximum current.
[6] Dependent on package type.
[7] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 kΩ series resistor.
Table 5. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
