Struct stm32_metapac::sdmmc::regs::Dlenr

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

The SDMMC_DLENR register contains the number of data bytes to be transferred. The value is loaded into the data counter when data transfer starts.

Tuple Fields

0: u32

Implementations

impl Dlenr

pub const fn datalength(&self) -> u32

Data length value This register can only be written by firmware when DPSM is inactive (DPSMACT = 0). Number of data bytes to be transferred. When DDR = 1 DATALENGTH is truncated to a multiple of 2. (The last odd byte is not transfered) When DATALENGTH = 0 no data will be transfered, when requested by a CPSMEN and CMDTRANS = 1 also no command will be transfered. DTEN and CPSMEN are cleared to 0.

pub fn set_datalength(&mut self, val: u32)

Data length value This register can only be written by firmware when DPSM is inactive (DPSMACT = 0). Number of data bytes to be transferred. When DDR = 1 DATALENGTH is truncated to a multiple of 2. (The last odd byte is not transfered) When DATALENGTH = 0 no data will be transfered, when requested by a CPSMEN and CMDTRANS = 1 also no command will be transfered. DTEN and CPSMEN are cleared to 0.

Trait Implementations

impl Clone for Dlenr

fn clone(&self) -> Dlenr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Dlenr

fn default() -> Dlenr

Returns the “default value” for a type.

impl PartialEq for Dlenr

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