LPC5410x User manual

2.1 20151218 •Added Table 89 “Device ID1 register values”.

•Added text to Section 4.5.47.1 “CPU Control register”: The user can assign Cortex-M0+ to be the

master CPU via this register if needed after it is brought out of reset by Cortex-M4.

•Added text to Section 4.6.3 “Brown-out detection”: On the LPC5410x, the BOD is enabled by

default after power-up. At this time the BOD is set to the lowest value (1.5v) with no factory trimming

applied. In the BOD block the interrupt portion is turned off and only the reset portion is on. After

POR/BOD resets, the BootROM takes over and applies the factory BOD trim value so that the trip

points become accurate. See the LPC5410x data sheet for BOD interrupt/reset voltage levels in the

BOD static characteristics.

•Added section Section 12.5.7 “Channel chaining”.

•Updated Figure 53 “System FIFO conceptual block diagram”.

•Updated description of 15:12,TIMEOUT VALUE; Specifies the maximum time value for timeout at

the timer position identified by TimeoutBase. Minimum time TimeoutValue - 1 (clocks of wdt_clk).

See Table 383 “Configuration register for USARTn (CFGUSART[0:3], address offset

[0x1000:0x1300]) bit description”.

•Updated the values in the sentence: TimeoutValue can be any value from 2 to 15. This gives a

maximum timeout range of 2 counts (too small to be useful) at the bottom end, up to 15 * 32,768

(491,520) counts at the upper end. See Section 24.5.7.1 “Receiver Timeout”

•Updated text in Table 468 “set_voltage routine”: Param1: desired frequency (in Hz); was: Param1:

desired frequency (in MHz).

•Removed text from Section 5.2 “General description”, list 3:

...or for monitoring analog inputs (comparators and internal voltage reference and temperature

sensor via one of the comparators).

•Removed comparator from Section 13.5 “General description”: This provides an extremely powerful

control tool - particularly when the SCT inputs and outputs are connected to other on-chip

resources (ADC triggers, other timers etc.) in addition to general-purpose I/O.

•Added AHBCLKDIV register should be set to 1 in: List item 2 “Select the IRC as the main clock and

set the AHBCLKDIV register to 1. See Table 45, Table 46, and Table 58.”, Section 5.3.4.2

“Programming Deep-sleep mode”.

•Added AHBCLKDIV register should be set to 1 in: List item 2 “Select the IRC as the main clock and

set the AHBCLKDIV register to 1. See Table 45, Table 46, and Table 58.”, Section 5.3.5.2

“Programming Power-down mode”.

•Added registers, DIRSET0, DIRCLR0, DIRNOT0. See Table 134 “Register overview: GPIO port

(base address 0x1C00 0000)” and Section 9.5.10 “GPIO port direction set registers”, Section 9.5.11

“GPIO port direction clear registers”, and Section 9.5.12 “GPIO port direction toggle registers”.

•Added note to Table 223 “SCT DMA 0 request register (DMAREQ0, address 0x5000 405C) bit

description” and Table 224 “SCT DMA 1 request register (DMAREQ1, address 0x5000 4060) bit

description”.

•Added remark to Section 4.5.37.5.1 “System PLL spread spectrum control register 0”: If the 32 kHz

RTC oscillator is used as the reference input to the PLL, then use fixed values SELI=1, SELP=6

and SELR=0, instead of applying the above rules. These values reduce the PLL loop bandwidth to

combat the effect of reference oscillator jitter on the PLL output signal.

•In Table 62 “Flash configuration register (FLASHCFG, main syscon: address 0x4000 0124) bit

description” replaced offset in table title to address 0x4000 0124.

NXP Semiconductors UM10850

Chapter 1: LPC5410x Introductory information

1.4 Architectural overview

The ARM Cortex-M4 includes three AHB-Lite buses, one system bus and the I-code and

D-code buses. One bus is dedicated for instruction fetch (I-code), and one bus is

dedicated for data access (D-code). The use of two core buses allows for simultaneous

operations if concurrent operations target different devices.

A multi-layer AHB matrix connects the CPU buses and other bus masters to peripherals in

a flexible manner that optimizes performance by allowing peripherals on different slaves

ports of the matrix to be accessed simultaneously by different bus masters. More

information on the multilayer matrix can be found in Section 2.1.3. Connections in the

multilayer matrix are shown in Figure 1.

APB peripherals are connected to the AHB matrix via two APB buses using separate

slave ports from the multilayer AHB matrix. This allows for better performance by reducing

collisions between the CPU and the DMA controller, and also for peripherals on the

asynchronous bridge to have a fixed clock that does not track the system clock.

1.5 ARM Cortex-M4 processor

The Cortex-M4 is a general purpose 32-bit microprocessor, which offers high performance

and very low power consumption. The Cortex-M4 offers a Thumb-2 instruction set, low

interrupt latency, interruptible/continuable multiple load and store instructions, automatic

state save and restore for interrupts, tightly integrated interrupt controller, and multiple

core buses capable of simultaneous accesses.

A 3-stage pipeline is 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.

Information about Cortex-M4 configuration options can be found in Chapter 32.

1.6 ARM Cortex-M0+ processor (present on LPC54102 devices)

The Cortex-M0+ is a general purpose 32-bit microprocessor with extremely low power

consumption. The Cortex-M0+ includes the bulk of the Thumb instruction set and a small

subset of Thumb-2 Instructions. The Cortex-M0+ has a 2-stage pipeline in order to

decrease power consumption, and includes a 32-cycle multiplier.

Information about Cortex-M0+ configuration options can be found in Chapter 32.
