AN725
To measure the data sheet numbers using an SiM3L1xx MCU Card and the AN725_PowerMode_8 example:
1. Configure the SiM3L1xx MCU Card according to the instructions in Section “5.2.1. Hardware Setup”.
2. Open the AN725_PowerMode_8 example in either Keil µVision or the Precision32 IDE.
3. Select the desired AHB clock rate using the #defines at the top of the file.
4. Compile and download the code to the device.
5. Disconnect the USB Debug Adapter.
6. Connect PB0.2 to PB1.5 using a short wire and the J21 and J22 headers.
7. Power down the board.
8. Power up the board. This will cause a power-on reset that will clear the settings of some modules (i.e.,
PMU).
9. Press PB1.7 to place the device in PM8. The PB1.5 LED will turn off.
10. Measure the power consumption of the device.
11. Press PB1.5 to wake the device from PM8. When this happens, the PB1.7 LED will turn on and the core
will sit in an infinite while(1) loop.
