[][src]Function xtensa_lx106_rt::set_crystal_frequency

pub fn set_crystal_frequency(crystal: CrystalFrequency)

Configure the internal PLL for a given crystal frequency

Most boards use a 26MHz crystal, and the PLL will be configured for this by default. If your board uses a 40MHz crystal, you'll need to use this method to get your clock running at the expected 80MHz
