Struct ROSC 

pub struct ROSC { /* private fields */ }

ROSC

Implementations

impl ROSC

pub const PTR: *const RegisterBlock = {0x400e8000 as *const rp235x_hal::rp235x_pac::rosc::RegisterBlock}

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

Return the pointer to the register block

pub unsafe fn steal() -> ROSC

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 - Ring Oscillator control

pub fn freqa(&self) -> &Reg<FREQA_SPEC>

0x04 - 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 fn freqb(&self) -> &Reg<FREQB_SPEC>

0x08 - For a detailed description see freqa register

pub fn random(&self) -> &Reg<RANDOM_SPEC>

0x0c - Loads a value to the LFSR randomiser

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

0x10 - Ring Oscillator pause control

pub fn div(&self) -> &Reg<DIV_SPEC>

0x14 - Controls the output divider

pub fn phase(&self) -> &Reg<PHASE_SPEC>

0x18 - Controls the phase shifted output

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

0x1c - Ring Oscillator Status

pub fn randombit(&self) -> &Reg<RANDOMBIT_SPEC>

0x20 - 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 fn count(&self) -> &Reg<COUNT_SPEC>

0x24 - 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.
