timer in low power mode.

[DevineFelix]

hi, my application with nrf51822 needs a clock keeping active when the chip enter system off mode or sub power modes. So when the system wakes up from low poer mode, the timer can still get a correct time without having to be updated. Does s110 have any api that can fullfil this requirement? thank you .

Hi

There are simple low power examples available on Nordic's Github page, both for System On and System Off, that show how to put the device to sleep and wake it up by pressing buttons.

I think you can read about how this actually works by looking at the current consumption guide and the low frequency clock model and perhaps the high frequency clock model. In the current consumption guide, specifically look at the "Low power mode with BLE softdevice" section
