What is the user manual for the lpc17xx?
User manual Rev. 2 — 19 August 2010 3 of 840 1.1 Introduction The LPC17xx is an ARM Cortex-M3 based microcontroller for embedded applications requiring a high level of integration and low power dissipation.
What happens when RTC is shut off in deep power down mode?
UM10360.pdf, chapter 4.8.4 says: “In Deep Power-down mode, power is shut off to the entire chip” […] That means all data that is not in the RTC backup registers is lost, and the chip will thus restart with a reset. Thanks for contributing an answer to Stack Overflow!
What do you need to know about um10360 lpc17xx?
NXP SemiconductorsUM10360 Chapter 1: LPC17xx Introductory information –I2S (Inter-IC Sound) interface for digital audio input or output, with fractional rate control. The I2S interface can be used with the GPDMA.
What is the structure of the LPC1768 Register?
A structure LPC_GPIOn (n= 0,1,2,3) contains all the registers for required for GPIO operation. Refer lpc17xx.h file for more info on the registers. Almost all the LPC1768 pins are multiplexed to support more than 1 function.
How are the LEDs turned on in LPC1768?
LEDs are turned ON by sending a high pulse using FIOSET register. After some time the LEDs are turned OFF by sending the low pulse using FIOCLR register. This is second approach in which FIOPIN register is used for both setting and clearing the PORT pins.
What is the CPU frequency of the um10360 lpc17xx?
High speed versions (LPC1769 and LPC1759) operate at up to a 120 MHz CPU frequency. Other versions operate at up to an 100 MHz CPU frequency. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals.
How big is the lpc17xx GPIO and SFR Register?
At the end of this tutorial you will be familiar with the lpc17xx GPIO and SFR registers and how to access them and configure them. As it is 32-bit architecture it can access 2^32 locations (4GB). This 4Gb of addressable locations are divided into ROM,RAM,GPIO,AHB Peripherals as shown in the below image.
