HFXO Initialization
Description
Initialize the HFXO oscillator.
Configure the HFXO for crystal or externally-generated waveform operation.
When operating in crystal mode, the value of the variable tuning capacitor C tune is sourced from a prioritized list of locations:
- Device-specific tuning value in Device Information page (factory calibrated PCB and SiP modules with integrated HFXO)
-
Device-specific tuning value in User Data page at offset 0x100 (manufacturing token
TOKEN_MFG_CTUNE
) -
Application-specific tuning value in configuration header
sl_device_init_hfxo_config.h
- Default value in EMLIB initialization struct for HFXO
