When connect, a logic 1 on the pin will cause the NMI to be processed. Select P2.10 as NMI pin At the first time, sure that NMI pin has logic 1 because if it connects with ground -> ISP is pulled low, system will enter in ISP mode. After that, call CLKPWR_PowerDown() to enter system in PowerDown mode (Note: In this time, NMI pin must be connected with ground to disable NMI interrupt). When system is PowerDowning..., pulls up NMI to logic 1, NMI occurs and wake-up system. @Directory contents: \EWARM: includes EWARM (IAR) project and configuration files \Keil: includes RVMDK (Keil)project and configuration files lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example makefile: Example's makefile (to build with GNU toolchain) nmi_powerdown.c: Main program @How to run: Hardware configuration: This example was tested only on: Keil MCB1700 with LPC1768 vers.1 These jumpers must be configured as following: - VDDIO: ON - VDDREGS: ON - VBUS: ON - Remain jumpers: OFF IAR LPC1768 KickStart vers.A These jumpers must be configured as following: - PWR_SEL: depend on power source - DBG_EN : ON - Remain jumpers: OFF Serial display configuration:(e.g: TeraTerm, Hyperterminal, Flash Magic...) 115200bps 8 data bit No parity 1 stop bit No flow control Running mode: This example can run on RAM/ROM mode. Note: If want to burn hex file to board by using Flash Magic, these jumpers need to be connected: - MCB1700 with LPC1768 ver.1: + RST: ON + ISP: ON - IAR LPC1768 KickStart vers.A: + RST_E: ON + ISP_E: ON (Please reference "LPC1000 Software Development Toolchain" - chapter 4 "Creating and working with LPC1000CMSIS project" for more information) Step to run: - Step 1: Build example. - Step 2: Burn hex file into board (if run on ROM mode) - Step 3: Connect UART0 on this board to COM port on your computer - Step 4: Configure hardware and serial display as above instruction - Step 5: Run example and observe on serial display + First, sure that NMI pin (P2.10) has logic 1 + Press "RESET" button to run example + Connect P2.10 with ground to disable NMI interrupt + Press '1' to enter system in DeepSleep mode + After sleeping..., pull up P2.10 to generate NMI interrupt to wake-up system (Pls see "LPC17xx Example Description" document - chapter "Examples > PWR > NMI_PowerDown" for more details) @Tip: - Open \EWARM\*.eww project file to run example on IAR - Open \RVMDK\*.uvproj project file to run example on Keil - On MCB1700 board, it doesn't have a wiring ground pin output, so you can use UMODE.3 instead (reference MCB1700 datasheet for more information)
