Implement LPC29xx power-down mode

Keywords:LPC29xx  power-down  MCU 

This application note by NXP Semiconductor describes the techniques necessary to place the LPC29xx device into power-down (PD) mode. The LPC29xx incorporates a sophisticated and complex power management system, says NXP. This application note will describe how to use the power management unit to place the MCU into a PD state while maintaining the ability to respond to its environment.

The Keil MCB2900 version 1 evaluation board with a LPC2919/01 is used in this application note. The board switches connected to external interrupt 4 and 5 are used as inputs. The external interrupts can be changed to other ports by modifying a 'define' in the code, so other board can also be used. Software configuration of the hardware will be discussed in detail in the software chapter.
