Any Current savings after enabling RTC clock.

I believe the HFINT will trigger after the 2 seconds, but not while waiting. But you should probably do the measurements to be sure.

Hi Simonr,

Assume in below code most of the time device is in do...while() loop. In this case whether High frequency clock will be executed ?

    do
    {
        bStartInputPinStatus = bsp_board_button_state_get(DATALOG_START_BUTTON_ID);
    while(bStartInputPinStatus == false);

    // Enter main loop.
    for (;;)
    {
        idle_state_handle();
    }

Thanks & Regards

Hi Vishnu

The RTC will only need the LFCLK. The HFINT will be turned on when needed (when the CPU is running or when a peripheral request it), and turned off when it isn't required.

Best regards,

Simon
