Type Alias rp2040_pac::rosc::ctrl::W

pub type W = W<CTRL_SPEC>;

Register CTRL writer

Aliased Type

struct W { /* private fields */ }

Implementations

impl W

pub fn freq_range(&mut self) -> FREQ_RANGE_W<'_, CTRL_SPEC>

Bits 0:11 - 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 enable(&mut self) -> ENABLE_W<'_, CTRL_SPEC>

Bits 12:23 - 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 unsafe fn bits(&mut self, bits: u32) -> &mut Self

Writes raw bits to the register.

Safety

Passing incorrect value can cause undefined behaviour. See reference manual
