Clock Initialization

Device Initialization

Description

Initialize the clock tree.

Automatically configures the clock tree to use the appropriate high- and low-frequency clock sources depending on which other device initialization components are present.

High Frequency Clocks

If the DPLL or HFRCO device init components are present, the HFRCO oscillator is used as the clock source for high frequency clock trees. Otherwise, if the HFXO device init component is present, the HFXO oscillator is used. If no high frequency oscillator device init component is present, the HFRCO oscillator is used with its default settings.

Low Frequency Clocks

If the LFXO device init component is present, the LFXO oscillator is used as the clock source for low frequency clock trees. Otherwise, the LFRCO oscillator is used.

Note

This module has a limited configurability. Users can override the code based on the project ask.
