Which part of library does S130 start HFClk automatically?

[nordicdev]

Hi, Could you please help me identify the file and function name that is used by the S130 softdevice to start HF clock automatically for ble advertising? I can see that Clock HAL : developer.nordicsemi.com/.../a00904.html does this, but where are these nrf_clock functions called from? When I look for "nrf_clock" in my BLE example project, it does not come up with any reference finds. (I can find "SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL);" inside ble_Stack_init, though.) Thanks.

Most likely Softdevice itself does this after you call SOFTDEVICE_HANDLER_INIT. You won't see actual call because SD is supplied as a binary. All sd_ prefixed functions are in fact only causing software interrupts that are intercepted by the binary code.

This is what I wanted to know. Great work, thanks!
