Implementations

impl<'a> HFXOMODE_W<'a>

pub fn xtal(self) -> &'a mut W

4-48 MHz crystal oscillator.

pub fn bufextclk(self) -> &'a mut W

An AC coupled buffer is coupled in series with HFXTAL_N, suitable for external sine wave (4-48 MHz). The sine wave should have a minimum of 200 mV peak to peak.

pub fn digextclk(self) -> &'a mut W

Digital external clock on HFXTAL_N pin. Oscillator is effectively bypassed.
