Single-chip 32-bit microcontrollers
processor clock rate. The second purpose of the APB divider is to allow power savings
when an application does not require any peripherals to run at the full processor rate.
Because the APB divider is connected to the PLL output, the PLL remains active (if it was
running) during Idle mode.
6.19 Emulation and debugging
The LPC2104/2105/2106 support emulation and debugging via a JTAG serial port. A trace
port allows tracing program execution. Each of these functions requires a trade-off of
debugging features versus device pins. Because the LPC2104/2105/2106 are provided in
a small package, there is no room for permanently assigned JTAG or Trace pins. An
alternate JTAG port allows an option to debug functions assigned to the pins used by the
primary JTAG port (see Section 6.8).
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 ow or even
entering the debug state. The debug communication channel is accessed as a
co-processor 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 ow. 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 1
6 of the CPU clock (CCLK) for the JTAG
interface to operate.
6.19.2 Embedded trace
Since the LPC2104/2105/2106 have signicant 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 ow of execution of the processor and provides a
list of all the instructions that were executed. Instruction trace is signicantly 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 cannot be traced
because of this restriction.
