1. General description
The LPC2212/2214 are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation
and embedded trace support, together with 128/256 kB of embedded high-speed flash
memory. A 128-bit wide memory interface and a unique accelerator architecture enable
32-bit code execution at maximum clock rate. For critical code size applications, the
alternative 16-bit Thumb mode reduces code by more than 30 % with minimal
performance penalty.
With their 144-pin package, low power consumption, various 32-bit timers, 8-channel
10-bit ADC, PWM channels and up to nine external interrupt pins these microcontrollers
are particularly suitable for industrial control, medical systems, access control and
point-of-sale. Number of available fast GPIOs ranges from up to 76 pins (with external
memory) through up to 112 pins (single-chip). With a wide range of serial communications
interfaces, they are also very well suited for communication gateways, protocol converters
and embedded soft modems as well as many other general-purpose applications.
Remark: Throughout the data sheet, the term LPC2212/2214 will apply to devices with
and without the /00 or /01 suffixes. The /00 or the /01 suffix will be used to differentiate
from other devices only when necessary.
2. Features
2.1 Key features brought by LPC2212/2214/01 devices
nFast GPIO ports enable port pin toggling up to 3.5 times faster than the original device.
They also allow for a port pin to be read at any time regardless of its function.
nDedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are
5 V tolerant when configured for digital I/O function(s).
nUART0/1 include fractional baud rate generator, auto-bauding capabilities and
handshake flow-control fully implemented in hardware.
nBuffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.
nSPI programmable data length and master mode enhancement.
nDiversified Code Read Protection (CRP) enables different security levels to be
implemented. This feature is available in LPC2212/2214/00 devices as well.
nGeneral purpose timers can operate as external event counters.
2.2 Key features common for all devices
n16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.

16/32-bit ARM microcontrollers
6. Functional description
Details of the LPC2212/2214 systems and peripheral functions are described in the
following sections.
6.1 Architectural overview
The ARM7TDMI-S is a general purpose 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM architecture is based on
Reduced Instruction Set Computer (RISC) principles, and the instruction set and related
decode mechanism are much simpler than those of microprogrammed Complex
Instruction Set Computers. This simplicity results in a high instruction throughput and
impressive real-time interrupt response from a small and cost-effective processor core.
Pipeline techniques are employed so that all parts of the processing and memory systems
can operate continuously. Typically, while one instruction is being executed, its successor
is being decoded, and a third instruction is being fetched from memory.
The ARM7TDMI-S processor also employs a unique architectural strategy known as
Thumb, which makes it ideally suited to high-volume applications with memory
restrictions, or applications where code density is an issue.
The key idea behind Thumb is that of a super-reduced instruction set. Essentially, the
ARM7TDMI-S processor has two instruction sets:
The standard 32-bit ARM set.
A 16-bit Thumb set.
The Thumb set’s 16-bit instruction length allows it to approach twice the density of
standard ARM code while retaining most of the ARM’s performance advantage over a
traditional 16-bit processor using 16-bit registers. This is possible because Thumb code
operates on the same 32-bit register set as ARM code.
Thumb code is able to provide up to 65 % of the code size of ARM, and 160 % of the
performance of an equivalent ARM processor connected to a 16-bit memory system.
6.2 On-chip flash program memory
The LPC2212/2214 incorporate a 128 kB and 256 kB flash memory system respectively.
This memory may be used for both code and data storage. Programming of the flash
memory may be accomplished in several ways. It may be programmed In System via the
serial port. The application program may also erase and/or program the flash while the
application is running, allowing a great degree of flexibility for data storage field firmware
upgrades, etc. When on-chip bootloader is used, 120/248 kB of flash memory is available
for user code.
The LPC2212/2214 flash memory provides a minimum of 100000 erase/write cycles and
20 years of data retention.
On-chip bootloader (as of revision 1.60) provides Code Read Protection (CRP) for the
LPC2212/2214 on-chip flash memory. When the CRP is enabled, the JTAG debug port,
external memory boot and ISP commands accessing either the on-chip RAM or flash
memory are disabled. However, the ISP flash erase command can be executed at any

16/32-bit ARM microcontrollers
time (no matter whether the CRP is on or off). Removal of CRP is achieved by erasure of
full on-chip user flash. With the CRP off, full access to the chip via the JTAG and/or ISP is
restored.
6.3 On-chip static RAM
On-chip static RAM may be used for code and/or data storage. The SRAM may be
accessed as 8 bit, 16 bit, and 32 bit. The LPC2212/2214 provide 16 kB of static RAM.
6.4 Memory map
The LPC2212/2214 memory maps incorporate several distinct regions, as shown in the
following figures.
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either
flash memory (the default) or on-chip static RAM. This is described in Section 6.18
“System control”.

6.5 Interrupt controller
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as Fast Interrupt reQuest (FIQ), vectored Interrupt Request (IRQ), and
non-vectored IRQ as defined by programmable settings. The programmable assignment
scheme means that priorities of interrupts from the various peripherals can be dynamically
assigned and adjusted.
The FIQ has the highest priority. If more than one request is assigned to FIQ, the VIC
combines the requests to produce the FIQ signal to the ARM processor. The fastest
possible FIQ latency is achieved when only one request is classified as FIQ, because then
the FIQ service routine can simply start dealing with that device. But if more than one
request is assigned to the FIQ class, the FIQ service routine can read a word from the VIC
that identifies which FIQ source(s) is (are) requesting an interrupt.

NXP Semiconductors LPC2212/2214
16/32-bit ARM microcontrollers
Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be assigned
to this category. Any of the interrupt requests can be assigned to any of the 16 vectored
IRQ slots, among which slot 0 has the highest priority and slot 15 has the lowest.
Non-vectored IRQs have the lowest priority.
The VIC combines the requests from all the vectored and non-vectored IRQs to produce
the IRQ signal to the ARM processor. The IRQ service routine can start by reading a
register from the VIC and jumping there. If any of the vectored IRQs are requesting, the
VIC provides the address of the highest-priority requesting IRQs service routine,
otherwise it provides the address of a default routine that is shared by all the non-vectored
IRQs. The default routine can read another VIC register to see what IRQs are active.
6.5.1 Interrupt sources
Table 4 lists the interrupt sources for each peripheral function. Each peripheral device has
one interrupt line connected to the Vectored Interrupt Controller, but may have several
internal interrupt flags. Individual interrupt flags may also represent more than one
interrupt source.

6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on chip peripherals. Peripherals should be connected to the appropriate pins
prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any
enabled peripheral function that is not mapped to a related pin should be considered
undefined.
6.7 External memory controller
The external Static Memory Controller (SMC) is a module which provides an interface
between the system bus and external (off-chip) memory devices. It provides support for
up to four independently configurable memory banks (16 MB each with byte lane enable
control) simultaneously. Each memory bank is capable of supporting SRAM, ROM, flash
EPROM, burst ROM memory, or some external I/O devices.
Each memory bank may be 8-bit, 16-bit, or 32-bit wide.
6.8 General purpose parallel I/O (GPIO) and Fast I/O
Device pins that are not connected to a specific peripheral function are controlled by the
parallel I/O registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back, as well as the current state of the port pins.
6.8.1 Features
Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
6.8.2 Features added with the Fast GPIO set of registers available on
LPC2212/2214/01 only
Fast GPIO registers are relocated to the ARM local bus for the fastest possible I/O
timing, enabling port pin toggling up to 3.5 times faster than earlier LPC2000 devices.
Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
All Fast GPIO registers are byte addressable.
Entire port value can be written in one instruction.
Ports are accessible via either the legacy group of registers (GPIOs) or the group of
registers providing accelerated port access (Fast GPIOs).

6.11 I2C-bus serial I/O controller
The I2C-bus is a bidirectional bus for inter-IC control using only two wires: a serial clock
line (SCL), and a serial data line (SDA). Each device is recognized by a unique address
and can operate as either a receiver-only device (e.g. an LCD driver or a transmitter with
the capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C-bus is a multi-master bus; it can be
controlled by more than one bus master connected to it.
The I2C-bus implemented in LPC2212/2214 supports a bit rate up to 400 kbit/s (Fast
I2C-bus).
6.11.1 Features
Standard I2C-bus compliant interface.
Easy to configure as Master, Slave, or Master/Slave.
Programmable clocks allow versatile rate control.
Bidirectional data transfer between masters and slaves.
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
The I2C-bus may be used for test and diagnostic purposes.
6.12 SPI serial I/O controller
The LPC2212/2214 each contain two SPIs. The SPI is a full duplex serial interface,
designed to be able to handle multiple masters and slaves connected to a given bus. Only
a single master and a single slave can communicate on the interface during a given data
transfer. During a data transfer the master always sends a byte of data to the slave, and
the slave always sends a byte of data to the master.
6.12.1 Features
Compliant with Serial Peripheral Interface (SPI) specification.
Synchronous, Serial, Full Duplex communication.
Combined SPI master and slave.
Maximum data bit rate of 18 of the input clock rate.
6.12.2 Features available in LPC2212/2214/01 only
Eight to 16 bits per frame.

NXP Semiconductors LPC2212/2214
16/32-bit ARM microcontrollers
When the SPI interface is used in Master mode, the SSEL pin is not needed (can be
used for a different function).
6.13 SSP controller (LPC2212/2214/01 only)
The SSP is a controller capable of operation on a SPI, 4-wire SSI, or Microwire bus. It can
interact with multiple masters and slaves on the bus. Only a single master and a single
slave can communicate on the bus during a given data transfer. Data transfers are in
principle full duplex, with frames of four to 16 bits of data flowing from the master to the
slave and from the slave to the master.
While the SSP and SPI1 peripherals share the same physical pins, it is not possible to
have both of these two peripherals active at the same time. Application can switch on the
fly from SPI1 to SSP and back.
6.13.1 Features
Compatible with Motorola’s SPI, Texas Instrument’s 4-wire SSI, and National
Semiconductor’s Microwire buses.
Synchronous serial communication.
Master or slave operation.
8-frame FIFOs for both transmit and receive.
Four to 16 bits per frame.
6.14 General purpose timers
The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an
externally supplied clock and optionally generate interrupts or perform other actions at
specified timer values, based on four match registers. It also includes four capture inputs
to trap the timer value when an input signal transitions, optionally generating an interrupt.
Multiple pins can be selected to perform a single capture or match function, providing an
application with ‘or’ and ‘and’, as well as ‘broadcast’ functions among them.
6.14.1 Features
A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
Timer or external event counter operation
Four 32-bit capture channels per timer that can take a snapshot of the timer value
when an input signal transitions. A capture event may also optionally generate an
interrupt.
Four 32-bit match registers that allow:
Continuous operation with optional interrupt generation on match.
Stop timer on match with optional interrupt generation.
Reset timer on match with optional interrupt generation.
Four external outputs per timer corresponding to match registers, with the following
capabilities:
Set LOW on match.
Set HIGH on match.

6.14.2 Features available in LPC2212/2214/01 only
The LPC2212/2214/01 can count external events on one of the capture inputs if the
external pulse lasts at least one half of the period of the PCLK. In this configuration,
unused capture lines can be selected as regular timer capture inputs, or used as external
interrupts.
Timer can count cycles of either the peripheral clock (PCLK) or an externally supplied
clock.
When counting cycles of an externally supplied clock, only one of the timer’s capture
inputs can be selected as the timer’s clock. The rate of such a clock is limited to
PCLK / 4. Duration of high/low levels on the selected CAP input cannot be shorter
than 1 / (2PCLK).
6.15 Watchdog timer
The purpose of the Watchdog is to reset the microcontroller within a reasonable amount of
time if it enters an erroneous state. When enabled, the Watchdog will generate a system
reset if the user program fails to ‘feed’ (or reload) the Watchdog within a predetermined
amount of time.
6.15.1 Features
Internally resets chip if not periodically reloaded.
Debug mode.
Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
Incorrect/incomplete feed sequence causes reset/interrupt if enabled.
Flag to indicate watchdog reset.
Programmable 32-bit timer with internal prescaler.
Selectable time period from (Tcy(PCLK) ×256 ×4) to (Tcy(PCLK) ×232 ×4) in multiples of
Tcy(PCLK) × 4.
6.16 Real-time clock
The RTC is designed to provide a set of counters to measure time when normal or idle
operating mode is selected. The RTC has been designed to use little power, making it
suitable for battery powered systems where the CPU is not running continuously (Idle
mode).
6.16.1 Features
Measures the passage of time to maintain a calendar and clock.
Ultra low power design to support battery powered systems.

Programmable reference clock divider allows adjustment of the RTC to match various
crystal frequencies.
6.17 Pulse width modulator
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC2212/2214. The Timer is designed to
count cycles of the peripheral clock (PCLK) and optionally generate interrupts or perform
other actions when specified timer values occur, based on seven match registers. The
PWM function is also based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires three
non-overlapping PWM outputs with individual control of all three pulse widths and
positions.
Two match registers can be used to provide a single edge controlled PWM output. One
match register (MR0) controls the PWM cycle rate, by resetting the count upon match.
The other match register controls the PWM edge position. Additional single edge
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an MR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, the MR0 match register controls the PWM cycle rate. The other match registers
control the two PWM edge positions. Additional double edge controlled PWM outputs
require only two match registers each, since the repetition rate is the same for all PWM
outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
6.17.1 Features
Seven match registers allow up to six single edge controlled or three double edge
controlled PWM outputs, or a mix of both types.
The match registers also allow:
Continuous operation with optional interrupt generation on match.
Stop timer on match with optional interrupt generation.
Reset timer on match with optional interrupt generation.
Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go HIGH at the beginning of each cycle unless the
output is a constant LOW. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.

NXP Semiconductors LPC2212/2214
16/32-bit ARM microcontrollers
Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.
Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
May be used as a standard timer if the PWM mode is not enabled.
A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
6.18 System control
6.18.1 Crystal oscillator
The oscillator supports crystals in the range of 1 MHz to 30 MHz. The oscillator output
frequency is called fosc and the ARM processor clock frequency is referred to as CCLK for
purposes of rate equations, etc. fosc and CCLK are the same value unless the PLL is
running and connected. Refer to Section 6.18.2 “PLL for additional information.
6.18.2 PLL
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input
frequency is multiplied up into the range of 10 MHz to 60 MHz with a Current Controlled
Oscillator (CCO). The multiplier can be an integer value from 1 to 32 (in practice, the
multiplier value cannot be higher than 6 on this family of microcontrollers due to the upper
frequency limit of the CPU). The CCO operates in the range of 156 MHz to 320 MHz, so
there is an additional divider in the loop to keep the CCO within its frequency range while
the PLL is providing the desired output frequency. The output divider may be set to divide
by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2,
it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and
bypassed following a chip Reset and may be enabled by software. The program must
configure and activate the PLL, wait for the PLL to Lock, then connect to the PLL as a
clock source. The PLL settling time is 100 µs.
6.18.3 Reset and wake-up timer
Reset has two sources on the LPC2212/2214: the RESET pin and Watchdog Reset. The
RESET pin is a Schmitt trigger input pin with an additional glitch filter. Assertion of chip
Reset by any source starts the Wake-up Timer (see Wake-up Timer description below),
causing the internal chip reset to remain asserted until the external Reset is de-asserted,
the oscillator is running, a fixed number of clocks have passed, and the on-chip flash
controller has completed its initialization.
When the internal Reset is removed, the processor begins executing at address 0, which
is the Reset vector. At that point, all of the processor and peripheral registers have been
initialized to predetermined values.
The Wake-up Timer ensures that the oscillator and other analog functions required for
chip operation are fully functional before the processor is allowed to execute instructions.
This is important at power on, all types of Reset, and whenever any of the aforementioned

functions are turned off for any reason. Since the oscillator and other functions are turned
off during Power-down mode, any wake-up of the processor from Power-down mode
makes use of the Wake-up Timer.
The Wake-up Timer monitors the crystal oscillator as the means of checking whether it is
safe to begin code execution. When power is applied to the chip, or some event caused
the chip to exit Power-down mode, some time is required for the oscillator to produce a
signal of sufficient amplitude to drive the clock logic. The amount of time depends on
many factors, including the rate of VDD ramp (in the case of power on), the type of crystal
and its electrical characteristics (if a quartz crystal is used), as well as any other external
circuitry (e.g., capacitors), and the characteristics of the oscillator itself under the existing
ambient conditions.
6.18.4 Code security (Code Read Protection - CRP)
This feature of the LPC2212/2214 allows the user to enable different levels of security in
the system so that access to the on-chip flash and use of the JTAG and ISP can be
restricted. When needed, CRP is invoked by programming a specific pattern into a
dedicated flash location. IAP commands are not affected by the CRP.
There are three levels of the Code Read Protection.
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding
flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is
required and flash field updates are needed but all sectors can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P0[14] pin, too. It
is up to the user’s application to provide (if needed) flash update mechanism using IAP
calls or call reinvoke ISP command to enable flash update via UART0.
Remark: Devices without the suffix /00 or /01 have only a security level equivalent to
CRP2 available.
6.18.5 External interrupt inputs
The LPC2212/2214 include up to nine edge or level sensitive External Interrupt Inputs as
selectable pin functions. When the pins are combined, external events can be processed
as four independent interrupt signals. The External Interrupt Inputs can optionally be used
to wake up the processor from Power-down mode.
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.

6.18.6 Memory mapping control
The Memory Mapping Control alters the mapping of the interrupt vectors that appear
beginning at address 0x0000 0000. Vectors may be mapped to the bottom of the on-chip
flash memory, or to the on-chip static RAM. This allows code running in different memory
spaces to have control of the interrupts.
6.18.7 Power control
The LPC2212/2214 support two reduced power modes: Idle mode and Power-down
mode. In Idle mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Idle mode and may generate
interrupts to cause the processor to resume execution. Idle mode eliminates power used
by the processor itself, memory systems and related controllers, and internal buses.
In Power-down mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Power-down mode and the logic levels of chip output pins remain
static. The Power-down mode can be terminated and normal operation resumed by either
a Reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Power-down mode reduces chip power
consumption to nearly zero.
A Power Control for Peripherals feature allows individual peripherals to be turned off if
they are not needed in the application, resulting in additional power savings.
6.18.8 APB
The APB divider determines the relationship between the processor clock (CCLK) and the
clock used by peripheral devices (PCLK). The APB divider serves two purposes. The first
is to provide peripherals with the desired PCLK via APB so that they can operate at the
speed chosen for the ARM processor. In order to achieve this, the APB may be slowed
down to 12to 14of the processor clock rate. Because the APB bus must work properly at
power-up (and its timing cannot be altered if it does not work since the APB divider control
registers reside on the APB), the default condition at reset is for the APB to run at 14of the
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 LPC2212/2214 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.

NXP Semiconductors LPC2212/2214
16/32-bit ARM microcontrollers
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
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 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 16 of the CPU clock (CCLK) for the JTAG
interface to operate.
6.19.2 Embedded trace macrocell
Since the LPC2212/2214 have 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
LPC2212/2214 contain a specific configuration of RealMonitor software programmed into
the on-chip flash memory.
