#[repr(transparent)]
pub struct Status(pub u32);

Indicates status of Hash peripheral.

Tuple Fields

0: u32

Implementations

impl Status

pub const fn waiting(&self) -> bool

If 1, the block is waiting for more data to process.

pub const fn set_waiting(&mut self, val: bool)

If 1, the block is waiting for more data to process.

pub const fn digest(&self) -> bool

For Hash, if 1 then a DIGEST is ready and waiting and there is no active next block already started. For Cryptographic uses, this will be set for each block processed, indicating OUTDATA (and OUTDATA2 if larger output) contains the next value to read out. This is cleared when any data is written, when New is written, for Cryptographic uses when the last word is read out, or when the block is disabled.

pub const fn set_digest(&mut self, val: bool)

For Hash, if 1 then a DIGEST is ready and waiting and there is no active next block already started. For Cryptographic uses, this will be set for each block processed, indicating OUTDATA (and OUTDATA2 if larger output) contains the next value to read out. This is cleared when any data is written, when New is written, for Cryptographic uses when the last word is read out, or when the block is disabled.

pub const fn error(&self) -> bool

If 1, an error occurred. For normal uses, this is due to an attempted overrun: INDATA was written when it was not appropriate. For Master cases, this is an AHB bus error; the COUNT field will indicate which block it was on.

pub const fn set_error(&mut self, val: bool)

If 1, an error occurred. For normal uses, this is due to an attempted overrun: INDATA was written when it was not appropriate. For Master cases, this is an AHB bus error; the COUNT field will indicate which block it was on.

pub const fn needkey(&self) -> bool

Indicates the block wants the key to be written in (set along with WAITING)

pub const fn set_needkey(&mut self, val: bool)

Indicates the block wants the key to be written in (set along with WAITING)

pub const fn neediv(&self) -> bool

Indicates the block wants an IV/NONE to be written in (set along with WAITING)

pub const fn set_neediv(&mut self, val: bool)

Indicates the block wants an IV/NONE to be written in (set along with WAITING)

pub const fn icbidx(&self) -> u8

If ICB-AES is selected, then reads as the ICB index count based on ICBSTRM (from CRYPTCFG). That is, if 3 bits of ICBSTRM, then this will count from 0 to 7 and then back to 0. On 0, it has to compute the full ICB, quicker when not 0.

pub const fn set_icbidx(&mut self, val: u8)

If ICB-AES is selected, then reads as the ICB index count based on ICBSTRM (from CRYPTCFG). That is, if 3 bits of ICBSTRM, then this will count from 0 to 7 and then back to 0. On 0, it has to compute the full ICB, quicker when not 0.

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Status

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Status

fn default() -> Status

Returns the “default value” for a type.

impl PartialEq for Status

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