Struct rp2040_pac2::rosc::regs::Ctrl

#[repr(transparent)]pub struct Ctrl(pub u32);

Ring Oscillator control

Implementations

impl Ctrl

pub const fn enable(&self) -> CtrlEnable

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.

pub fn set_enable(&mut self, val: CtrlEnable)

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.

pub const fn freq_range(&self) -> CtrlFreqRange

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

pub fn set_freq_range(&mut self, val: CtrlFreqRange)

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
