CONFIG_CMU_HFRCO_FREQ

Internal high frequency RC oscillator frequency

Type: int

Help

Set the internal high frequency RC oscillator frequency in Hz. This should be set by the
board's defconfig. Only supported values may be used here. Setting this to 0, skips the
configuration of the high frequency RC oscillator completely. This may be desired, if
the bootloader already configured it properly or the device's default clock source should
be used with it's default configuration.
