Struct CcRng 

pub struct CcRng { /* private fields */ }

CRYPTOCELL RNG engine

Implementations

impl CcRng

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

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

pub const fn rng_imr(self) -> Reg<RngImr, RW>

Interrupt mask register. Each bit of this register holds the mask of a single interrupt source.

pub const fn rng_isr(self) -> Reg<RngIsr, R>

Interrupt status register. Each bit of this register holds the interrupt status of a single interrupt source. If corresponding RNG_IMR bit is unmasked, an interrupt is generated.

pub const fn rng_icr(self) -> Reg<RngIcr, W>

Interrupt clear register. Writing a 1 bit into a field in this register will clear the corresponding bit in RNG_ISR.

pub const fn trng_config(self) -> Reg<TrngConfig, RW>

TRNG ring oscillator length configuration

pub const fn trng_valid(self) -> Reg<TrngValid, R>

This register indicates if TRNG entropy collection is valid.

pub const fn ehr_data(self, n: usize) -> Reg<u32, R>

Description collection: The entropy holding registers (EHR) hold 192-bits random data collected by the TRNG. The initial EHR_DATA[0] register holds the least significant bits [31:0] of the random data value.

pub const fn noise_source(self) -> Reg<NoiseSource, RW>

This register controls the ring oscillator circuit used as a noise source.

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

Sample count defining the number of CPU clock cycles between two consecutive noise source samples.

pub const fn autocorr_statistic(self) -> Reg<AutocorrStatistic, RW>

Statistics counter for autocorrelation test activations. Statistics collection is stopped if one of the counters reach its limit of all ones.

pub const fn trng_debug(self) -> Reg<TrngDebug, RW>

Debug register for the TRNG. This register is used to bypass TRNG tests in hardware.

pub const fn rng_sw_reset(self) -> Reg<RngSwReset, W>

Reset the RNG engine.

pub const fn rng_busy(self) -> Reg<RngBusy, R>

Status register for RNG engine activity.

pub const fn trng_reset(self) -> Reg<TrngReset, W>

Reset the TRNG, including internal counter of collected bits and registers EHR_DATA and TRNG_VALID.

pub const fn rng_hw_flags(self) -> Reg<RngHwFlags, R>

Hardware configuration of RNG engine. Reset value holds the supported features.

pub const fn rng_clk(self) -> Reg<RngClk, W>

Control clock for the RNG engine.

pub const fn rng_dma(self) -> Reg<RngDma, RW>

Writing to this register enables the RNG DMA engine.

pub const fn rng_dma_rosc_len(self) -> Reg<RngDmaRoscLen, RW>

This register defines which ring oscillator length configuration should be used when using the RNG DMA engine.

pub const fn rng_dma_sram_addr(self) -> Reg<RngDmaSramAddr, RW>

This register defines the start address in TRNG SRAM for the TRNG data to be collected by the RNG DMA engine.

pub const fn rng_dma_samples_num(self) -> Reg<RngDmaSamplesNum, RW>

This register defines the number of 192-bits samples that the RNG DMA engine collects per run.

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

This register defines the maximum number of CPU clock cycles per TRNG collection of 192-bits samples. If the number of cycles for a collection exceeds this threshold the WATCHDOG interrupt is triggered.

pub const fn rng_dma_busy(self) -> Reg<RngDmaBusy, R>

Status register for RNG DMA engine activity.

Trait Implementations

impl Clone for CcRng

fn clone(&self) -> CcRng

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for CcRng

fn eq(&self, other: &CcRng) -> 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.
