Struct XOSC 

pub struct XOSC { /* private fields */ }

Controls the crystal oscillator

Implementations

impl XOSC

pub const PTR: *const RegisterBlock = {0x40048000 as *const rp235x_hal::rp235x_pac::xosc::RegisterBlock}

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

Return the pointer to the register block

pub unsafe fn steal() -> XOSC

Steal an instance of this peripheral

Safety

Ensure that the new instance of the peripheral cannot be used in a way that may race with any existing instances, for example by only accessing read-only or write-only registers, or by consuming the original peripheral and using critical sections to coordinate access between multiple new instances.

Additionally, other software such as HALs may rely on only one peripheral instance existing to ensure memory safety; ensure no stolen instances are passed to such software.

Methods from Deref<Target = RegisterBlock>

pub fn ctrl(&self) -> &Reg<CTRL_SPEC>

0x00 - Crystal Oscillator Control

pub fn status(&self) -> &Reg<STATUS_SPEC>

0x04 - Crystal Oscillator Status

pub fn dormant(&self) -> &Reg<DORMANT_SPEC>

0x08 - Crystal Oscillator pause control

pub fn startup(&self) -> &Reg<STARTUP_SPEC>

0x0c - Controls the startup delay

pub fn count(&self) -> &Reg<COUNT_SPEC>

0x10 - A down counter running at the xosc frequency which counts to zero and stops. Can be used for short software pauses when setting up time sensitive hardware. To start the counter, write a non-zero value. Reads will return 1 while the count is running and 0 when it has finished. Minimum count value is 4. Count values <4 will be treated as count value =4. Note that synchronisation to the register clock domain costs 2 register clock cycles and the counter cannot compensate for that.

Trait Implementations
