Struct rp_pac::rosc::Rosc

pub struct Rosc { /* private fields */ }

Implementations

impl Rosc

pub const unsafe fn from_ptr(ptr: *mut ()) -> Self

pub const fn as_ptr(&self) -> *mut ()

pub const fn ctrl(self) -> Reg<Ctrl, RW>

Ring Oscillator control

pub const fn freqa(self) -> Reg<Freqa, RW>

The FREQA & FREQB registers control the frequency by controlling the drive strength of each stage The drive strength has 4 levels determined by the number of bits set Increasing the number of bits set increases the drive strength and increases the oscillation frequency 0 bits set is the default drive strength 1 bit set doubles the drive strength 2 bits set triples drive strength 3 bits set quadruples drive strength For frequency randomisation set both DS0_RANDOM=1 & DS1_RANDOM=1

pub const fn freqb(self) -> Reg<Freqb, RW>

For a detailed description see freqa register

pub const fn random(self) -> Reg<u32, RW>

Loads a value to the LFSR randomiser

pub const fn dormant(self) -> Reg<Dormant, RW>

Ring Oscillator pause control

pub const fn div(self) -> Reg<Div, RW>

Controls the output divider

pub const fn phase(self) -> Reg<Phase, RW>

Controls the phase shifted output

pub const fn status(self) -> Reg<Status, RW>

Ring Oscillator Status

pub const fn randombit(self) -> Reg<Randombit, RW>

This just reads the state of the oscillator output so randomness is compromised if the ring oscillator is stopped or run at a harmonic of the bus frequency

pub const fn count(self) -> Reg<Count, RW>

A down counter running at the ROSC frequency which counts to zero and stops. To start the counter write a non-zero value. Can be used for short software pauses when setting up time sensitive hardware.

Trait Implementations

impl Clone for Rosc

fn clone(&self) -> Rosc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for Rosc

fn eq(&self, other: &Rosc) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
