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) \ No newline at end of file
