8. Functional description

8.1 Architectural overview

The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and the D-code bus (see Figure 1 system bus and are used similarly to Tightly Coupled Memory (TCM) interfaces: one bus dedicated for instruction fetch (I-code) and one bus for data access (D-code). The use of two core buses allows for simultaneous operations if concurr ent operations target dif ferent devices.

The LPC1759/58/56/54/52/51 use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and other bus masters to peripherals in a flexible manner that optimizes performance by allowing peripherals that are on different slaves ports of th e matrix to be accessed simultaneously by different bus masters.

8.2 ARM Cortex-M3 processor

The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high performance and very low power consumption. The ARM Cortex-M3 offer s ma ny new features, including a Thumb-2 instruction set, low interrupt latency, hardware division, hardware single-cycle multiply, interruptable/continuable multiple load and store instructions, automatic state save and restore for interrupts, tightly integrated interrupt controller with wakeup interrupt controller, and multiple core buses capable of simultaneous accesses.

). The I-code and D-code core buses are faster than the

Pipeline techniques are employed so that all part s of the pro cessing and memory systems can operate continuously. Typically , while on e in struction is b eing e xecuted, its successor is being decoded, and a third instruction is being fetched from memory.

The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical Reference Manual that can be found on official ARM website.

8.3 On-chip flash program memory

The LPC1759/58/56/54/52/51 contain up to 512 kB of on-chip flash memory. A new two-port flash accelerator maximizes performance for use with the two fast AHB-Lite buses.

8.4 On-chip SRAM

The LPC1759/58/56/54/52/51 contain a total of up to 64 kB on-chip static RAM memory. This includes the main 32/16/8 kB SRAM, accessible by the CPU and DMA co ntroller on a higher-speed bus, and up to two additional 16 kB each SRAM blocks situated on a separate slave port on the AHB multilayer matrix.

This architecture allows CPU and DMA accesses to be spread over three separate RAMs that can be accessed simultaneously.

NXP Semiconductors

8.5 Memory Protection Unit (MPU)

The LPC1759/58/56/54/52/51 have a Memory Protection Unit (MPU) which can be used to improve the reliability of an embedded system by protecting critical data within the user application.

The MPU allows separating processing tasks by disallowing access to each other's data, disabling access to memory regions, allowing memory regions to be defined as re ad -onl y and detecting unexpected memory accesses that could potentially break the system.

The MPU separates the memory into distinct regions and implements protection by preventing disallowed accesses. The MPU supports up to 8 regions each of which can be divided into 8 subregions. Accesses to memory locations that are not defined in the MPU regions, or not permitted by the region settin g , will ca use the Memory Management Fault exception to take place.

8.6 Memory map

The LPC1759/58/56/54/52/51 incorporate several distinct memory regions, shown in the following figures. Figure 3 user program viewpoint following reset. The interrupt vector area supports address remapping.

shows the overall map of the entire address space from the

The AHB peripheral area is 2 MB in size, and is divided to allow for up to 128 peripherals. The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals. Each peripheral of either type is allocated 16 kB of space. This allows simplifying the address decoding for each peripheral.

8.7 Nested Vectored Interrupt Controller (NVIC)

The NVIC is an integral part of the Cortex-M3. The tight coup ling to the CPU allows for low interrupt latency and efficient processing of late arriving interrupts.

8.7.1 Features

• Controls system exceptions and peripheral interrupts

• In the LPC1759/58/56/54/52/51, the NVIC supports 33 vectored interrupts

• 32 programmable interrupt priority levels, with hardware priority level masking

• Relocatable vector table

• Non-Maskable Interrupt (NMI)

• Software interrupt generation

8.7.2 Interrupt sources

Each peripheral device has one interrupt line con nected to the NVIC but may have several interrupt flags. Individual interrupt flags may also represent more than one interrupt source.

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

Any pin on Port 0 and Port 2 (total of 30 pins) regardless of the selected function, can be programmed to generate an interrupt on a rising edge, a falling edge, or both.

8.8 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.

Most pins can also be configured as open-drain outputs or to have a pull-up, pull- down, or no resistor enabled.

8.9 General purpose DMA controller

The GPDMA is an AMBA AHB compliant peripheral allowing selected LPC1759/58/56/54/52/51 peripherals to have DMA support.

The GPDMA enables peripheral-to-memory, memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transactions. The source and destination areas can each be either a memory region or a peripheral, and can be accessed through the AHB master. The GPDMA controller allows data transfers between the USB and Ethernet (LPC1758 only) controllers and the various on-chip SRAM areas. The supported APB peripherals are SSP0/1, all UARTs, the I and the DAC. Two match signals for each timer can be used to trigger DMA transfers.

S-bus interface, the ADC,

Remark: Note that the DAC is not available on the LPC1752/51, and the I is not available on the LPC1754/52/51.

8.10 Fast general purpose parallel I/O

Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of outputs simult an eously. The value of the output register may be read back as well as the current state of the port pins.

LPC1759/58/56/54/52/51 use accelerated GPIO functions:

• GPIO registers are accessed th ro ug h the AHB mu ltila ye r bu s so th at th e fa ste st

possible I/O timing can be achieved.

• Mask registers allow treating sets of port bits as a group, leaving other bit s

unchanged.

• All GPIO registers are byte and half-word addressable.

• Entire port value can be written in one instruction.

• Support for Cortex-M3 bit banding.

• Support for use with the GPDMA controller.

The Universal Serial Bus (USB) is a 4-wire bus that supports communication between a host and one or more (up to 127) peripherals. The host controller allocates the USB bandwidth to attached devices through a token-based protocol. The bus supports hot plugging and dynamic configuration of the devices. All transactions are initiated by the host controller.

The LPC1759/58/56/54 USB interface includes a device, Host, and OTG controller with on-chip PHY for device and Host functions. The OTG switchin g pro tocol is supported through the use of an external controller. Details on typical USB interfacing solutions can be found in Section 15.1

8.21 General purpose 32-bit timers/external event counters

The LPC1759/58/56/54/52/51 include four 32-bit timer/counters. The timer/counter is designed to count cycles of the system derived clock or an externally-supplied clock. It can optionally generate interrupts, generate timed DMA request s, or perform other actions at specified timer values, based on four match registers.

NXP Semiconductors

• Up to two match registers can be used to generate timed DMA requests.

8.22 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 LPC1759/58/56/54/52/51. The Timer is designed to count cycles of the system derived clock an d optionally switch pins, genera te interrupts or perform other actions when specified tim er valu es occu r, based on seven match registers. The PWM function is in addition to these features, and is base d 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 (PWMMR0) 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 re gister 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 PWMMR0 match occurs.

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

– Do nothing on match.

Three match registers can be used to provide a PWM output with both edges controlled. Again, the PWMMR0 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).

8.22.1 Features

• LPC1759/58/56/54/52/51 has one PWM block with Counter or Timer operation (may

use the peripheral clock or one of the capture inputs as the clock source).

• Seven match registers allow up to 6 single edge controlled or 3 double edge

controlled PWM outputs, or a mix of both types. The match registers also allow:

– Continuous operation with optional interrupt generation on match. – St op 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.

8.24 Quadrature Encoder Interface (QEI)

A quadrature encoder, also known as a 2-channel incremental encoder, converts angular displacement into two pulse signals. By monitoring both the number of pulses and the relative phase of the two signals, the user ca n tr ack th e position, d ire ction of r otation, and velocity. In addition, a third channel, or index signal, can be used to reset the position counter. The quadrature encoder interface decodes the digital pulses from a quadrature encoder wheel to integrate position over time and determine direction of rotation. In addition, the QEI can capture the velocity of the encoder wheel.

Any bits of the timer/compare can be masked such that they do no t contribute to the match detection. The repetitive interrupt timer can be used to create an interrupt that repeats at predetermined intervals.

The purpose of the watchdog is to reset the microcontroller within a reasonable amo unt 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.

8.27.1 Features

8.28 RTC and backup registers

The RTC is a set of counters for measuring ti me when system power is on, and op tionally when it is off. The RTC on the LPC1759/58/56/54/52/51 is designed to have extremely low power consumption, i.e. less than 1 A. The RTC will typically run from the main chip power supply, conserving battery power while the rest of the device is powered up. When operating from a battery, the RTC will continue working down to 2.1 V. Battery power can be provided from a standard 3 V Lithium button cell.

An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion of the RTC, moving most of the power consumption out of the time counting function.

The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way that will provide less than 1 second per day error when operated at a constant voltage and temperature.

The RTC contains a small set of backup registers (20 bytes) for holding data while the main part of the LPC1759/58/56/54/52/51 is powered off.

The RTC includes an alarm function that can wake up the LPC1759/58/56/54/52/51 from all reduced power modes with a time resolution of 1 s.

8.29 Clocking and power control

8.29.1 Crystal oscillators

The LPC1759/58/56/54/52/51 include three independent oscillators. These are the main oscillator, the IRC oscillator, and the RTC oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Any of the three clock sources can be chosen by software to drive the main PLL and ultimately the CPU.

Following reset, the LPC1759/58/56/54/52/51 will operate from the Internal RC oscillator until switched by software. This allows systems to operate without any external crystal a nd the bootloader code to operate at a known frequency.

8.29.1.1 Internal RC oscillator

The IRC may be used as the clock source for the WDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 4 MHz. The IRC is trimmed to 1 % accuracy over the entire voltage and temperature range.

Upon power-up or any chip reset, the LPC1759/58/56/54/52/51 use the IRC as the clock source. Software may later switch to one of the other available clock sources.

8.29.1.2 Main oscillator

The main oscillator can be used as the clock source for the CPU, with or without using the PLL. The main oscillator also provides the clock source for the dedicated USB PLL.

The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency , by the m ain PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock

NXP Semiconductors

8.29.2 Main PLL (PLL0)

The PLL0 accepts an input clock frequency in the range of 32 kHz to 25 MHz. The input frequency is multiplied up to a high frequency, then divided down to provide the actual clock used by the CPU and/or the USB block.

The PLL0 input, in the range of 32 kHz to 25 MHz, may initially be divided down by a value ‘N’, which may be in the range of 1 to 256. This input division provides a wide range of output frequencies from the same input frequency.

Following the PLL0 input divider is the PLL0 multiplier. This can multiply the input divider output through the use of a Current Controlled Oscillator (CCO) by a value ‘M’, in the range of 1 through 32768. The resulting frequency must be in the range of 275 MHz to 550 MHz. The multiplier works by dividing the CCO output by the value of M, then using a phase-frequency detector to compare the divided CCO output to the multiplier input. The error value is used to adjust the CCO frequency.

The PLL0 is turned off and bypassed following a chip Reset and by entering Power -down mode. PLL0 is enabled by software only. The program must configure and activate the PLL0, wait for the PLL0 to lock, and then connect to the PLL0 as a clock source.

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

8.29.3 USB PLL (PLL1)

The LPC1759/58/56/54/52/51 contain a secon d , de dicated USB PLL1 to pr ovide clocking for the USB interface.

The PLL1 receives its clock input from the main oscillator only and provides a fixed 48 MHz clock to the USB block only. The PLL1 is disabled and powered of f on reset. If the PLL1 is left disabled, the USB clock will be supplied by the 48 MHz clock from the main PLL0.

The PLL1 accepts an input clock frequency in the range of 10 MHz to 25 MHz only. The input frequency is multiplied up the range of 48 MHz for the USB clock using a Current Controlled Oscillators (CCO). It is insured that the PLL1 output has a 50 % duty cycle.

8.29.4 Wake-up timer

The LPC1759/58/56/54/52/51 begin operation at power-up and when awakened from Power-down mode by using the 4 MHz IRC oscillator as the clock source. This allows chip operation to resume quickly. If the main oscillator or the PLL is needed by the application, software will need to enable these features and wait for them to stabilize before they are used as a clock source.

When the main oscillator is initially activated, the wake-up timer allows sof twa re to ensure that the main oscillator is fully functional before the processor uses it as a clock source and starts 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 to check whether it is safe to begin code execution. When power is applied to the chip, or when 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 man y factors, including the rate of V

There are fo ur special modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL va lues, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, Peripher al Power Control allows shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Each of the peripherals has its own clock divider which provides even better power control.

Integrated PMU (Power Management Unit) automatically adjust internal regulators to minimize power consumption during Sleep, Deep sleep, Power-down, and Deep power-down modes.

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

The LPC1759/58/56/54/52/51 also implement a separate power domain to allow turning off power to the bulk of the device while maintaining operation of the RTC and a small set of registers for storing data during any of the power-down modes.

8.29.5.1 Sleep mode

When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling th e clock to the ARM core.

In Sleep mode, execution of instructions is suspended until either a Reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses.

8.29.5.2 Deep-sleep mode

In Deep-sleep 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 Deep-sleep mode and the logic levels of chip pins remain static. The output of the IRC is disabled but the IRC is not powered down for a fast wake-up later. The RTC oscillator is not stopped because the RTC interrupts may be used as the wake-up source. The PLL is automatically turned off and disconnected. The CCLK and USB clock dividers automatically get reset to zero.

The Deep-sleep 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, Deep-sleep mode reduces chip power consumption to a very low value. Power to the flash memory is left on in Deep-sleep mode, allowing a very quick wake-up.

Product data sheet Rev. 8.6 — 18 August 2015 32 of 80

NXP Semiconductors

On wake-up from Deep-sleep mode, the code execution and peripherals activities will resume after 4 cycles expire if the IRC was used before entering Deep-sleep mode. If the main external oscillator was used, the code execution will resume when 4096 cycles expire. PLL and clock dividers need to be reconfigured accordingly.

8.29.5.3 Power-down mode

Power-down mode does everything that Deep-sleep mode does, but also turns off the power to the IRC oscillator and the flash memory. This saves more power but requires waiting for resumption of flash operation before execution of code or data access in the flash memory can be accomplished.

On the wake-up of Power-down mode, if the IRC was used before entering Power-down mode, it will take IRC 60 s to start-up. After this 4 IRC cycles will expire before the code execution can then be resumed if the code was running from SRAM. In the meantime, the flash wake-up timer then counts 4 MHz IRC clock cycles to make the 100 s flash start-up time. When it times out, access to the flash will be allowed. Users need to reconfigure the PLL and clock dividers accordingly.

8.29.5.4 Deep power-down mode

The Deep power-down mode can only be entered from the RTC block. In Deep power-down mode, power is shut off to the entire chip with the exception of the RTC module and the RESET

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

pin.

The LPC1759/58/56/54/52/51 can wake up from Deep power-down mode via the RESET pin or an alarm match event of the RTC.

8.29.5.5 Wakeup interrupt controller

The Wakeup Interrupt Controller (WIC) allows the CPU to automatically wake up from any enabled priority interrupt that can occur while the clocks are stopped in Deep sleep, Power-down, and Deep power-down modes.

The Wakeup Interrupt Controller (WIC) works in connection with the Nested Vectored Interrupt Controller (NVIC). When the CPU enters Deep sleep, Power-down, or Deep power-down mode, the NVIC sends a mask of the current interrupt situation to the WIC.This mask includes all of the interrupts that are both enabled and of sufficient priority to be serviced immediately . With this information, the WIC simply notices when one of the interrupts has occurred and then it wakes up the CPU.

The Wakeup Interrupt Controller (WIC) eliminates the need to periodically wake up the CPU and poll the interrupts resulting in additional power savings.

8.29.6 Peripheral power control

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.

8.29.7 Power domains

The LPC1759/58/56/54/52/51 provide two independent power domains that allow the bulk of the device to have power removed while maintaining operation of the RTC and the backup Registers.

On the LPC1759/58/56/54/52/51, I/O pads are powered by the 3 .3 V (V the V

pin powers the on-chip voltage regulato r which in tur n provide s powe r to

) pins, while

the CPU and most of the peripherals. Depending on the LPC1759/58/56/54/52/51 application, a design can use two power

options to manage power consumption. The first option assumes that power consumption is not a concern and the design ties the

and V

pins together. This app roach requires only one 3.3 V power supply for both pads, the CPU, and peripherals. While this solution is simple, it does not support powering down the I/O pad ring “on the fly” while keeping the CPU and peripherals alive.

The second option uses two power supplies; a 3.3 V supply for the I/O pads (V a dedicated 3.3 V supply for the CPU (V

The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of power to operate, which can be supplied by an external battery. The device core power (V

8.30.1 Reset

Reset has four sources on the LPC17xx: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET trigger input pin. Assertion of chip Reset by any source, once the operating voltag e attains a usable level, causes the RSTOUT description in Section 8.29.4

until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks have passed, and the flash controller has completed its initialization. Once reset is de-asserted, or, in case of a BOD-triggered reset, once the voltage rises above the BOD threshold, the RSTOUT

pin goes HIGH.

When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values.

8.30.2 Brownout detection

The LPC1759/58/56/54/52/51 include 2-stage monitoring of the voltage on the V

the Vectored Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a dedicated status register.

The second stage of low-voltage detection asserts reset to inactivate the LPC1759/58/56/54/52/51 when the voltage on the V This reset prevents alteration of the flash as operation of the various elements of the chip would otherwise become unreliable due to low voltage. The BOD circuit maintains this reset down below 1 V, at which point the power-on reset circuitry maintains the overall reset.

Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event loop to sense the condition.

pins falls below 1.85 V.

CAUTION

8.30.3 Code security (Code Read Protection - CRP)

This feature of the LPC1759/58/56/54/52/51 allows user to enable different levels of security in the system so that access to the on-chip flash an d 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 JT AG pins and the ISP. This mode effectively disables ISP override using P2[10] 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.

If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.

8.30.4 APB interface

The APB peripherals are split into two separate APB buses in order to distribute the bus bandwidth and thereby reducing stalls caused by contention between the CPU and the GPDMA controller.

1. LPC1751FBD80 with device ID 25001110 does not support CRP feature. LPC1751FBD80 with device ID 25001118 does support CRP. See errata note in ES_LPC1751.

8.30.5 AHB multilayer matrix

The LPC1759/58/56/54/52/51 use an AHB multilayer matrix. This matrix connects the instruction (I-code) and data (D-code) CPU buses of the ARM Cortex-M3 to the flash memory, the main (32 kB) static RAM, and the Boot ROM. The GPDMA can also access all of these memories. The peripheral DMA controllers, Ethernet (LPC1758 only) and USB, can access all SRAM blocks. Additionally, the matrix connects the CPU system bus and all of the DMA controllers to the various peripheral functions.

8.30.6 External interrupt inputs

The LPC1759/58/56/54/52/51 include up to 30 edge sensitive interrupt inputs combined with one level sensitive external interrupt input as selectable pin function. The external interrupt input can optionally be used to wake up the processor from Power-down mode.

8.30.7 Memory mapping control

The Cortex-M3 incorporates a mechanism that allows remapping the interrupt vector table to alternate locations in the memory map. This is controlled via the Vector Table Offset Register contained in the NVIC.

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address space. The vector table must be located on a 128 word (512 byte) boundary because the NVIC on the LPC1759/58/56/54/52/51 is configured for 128 total interrupts.

8.31 Emulation and debugging

Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and trace functions are supported in addition to a standard JTAG debug and parallel trace functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four watch points.

15.2 Crystal oscillator XTAL input and component selection

LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

The input voltage to the on-chip oscillators is limited to 1.8 V . If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled th rough a cap acitor wi th C

= 100 pF. To limit the in put voltage to the specified range, choose an additional

capacitor to ground C

which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave

mode, a minimum of 200 mV(RMS) is needed.

Fig 34. Slave mode operation of the on-chip oscillator

In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 34

), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected.

External components and models used in oscillation mode are shown in Figure 35

15.3 XTAL Printed-Circuit Board (PCB) layout guidelines

The crystal should be connected on the PCB as close as possible to the oscillator input and output pins of the chip. Take care that the load capacitors C third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plain. Loops must be made as small as possible in

order to keep the noise coupled in via the PCB as small as possible. Also parasitic s should stay as small as possible. Values of C accordingly to the increase in parasitics of the PCB layout.

15.4 Standard I/O pin configuration

Figure 36 shows the possible pin modes for standard I/O pins with analog input function:

• Digital output driver: Open-drain mode en ab le d/ disa b led

• Digital input: Pull-up enabled/disabled

• Digital input: Pull-down enabled/disabled

• Digital input: Repeater mode enabled/disabled

• Analog input

The default configuration for standard I/O pins is input with pull-up enabled. The weak MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.
