sourcepub const fn freq_range(&self) -> FreqRange
pub const fn freq_range(&self) -> FreqRange
Controls the number of delay stages in the ROSC ring LOW uses stages 0 to 7 MEDIUM uses stages 0 to 5 HIGH uses stages 0 to 3 TOOHIGH uses stages 0 to 1 and should not be used because its frequency exceeds design specifications The clock output will not glitch when changing the range up one step at a time The clock output will glitch when changing the range down Note: the values here are gray coded which is why HIGH comes before TOOHIGH
sourcepub fn set_freq_range(&mut self, val: FreqRange)
pub fn set_freq_range(&mut self, val: FreqRange)

sourcepub const fn enable(&self) -> Enable
pub const fn enable(&self) -> Enable
On power-up this field is initialised to ENABLE The system clock must be switched to another source before setting this field to DISABLE otherwise the chip will lock up The 12-bit code is intended to give some protection against accidental writes. An invalid setting will enable the oscillator.
