Register DLR writer

Implementations

impl W

pub fn dl( &mut self ) -> FieldWriterRaw<'_, u32, DLR_SPEC, u32, u32, Unsafe, 32, 0>

Bits 0:31 - Data length Number of data to be retrieved (value+1) in indirect and status-polling modes. A value no greater than 3 (indicating 4 bytes) should be used for status-polling mode. All 1s in indirect mode means undefined length, where QUADSPI will continue until the end of memory, as defined by FSIZE. 0x0000_0000: 1 byte is to be transferred 0x0000_0001: 2 bytes are to be transferred 0x0000_0002: 3 bytes are to be transferred 0x0000_0003: 4 bytes are to be transferred … 0xFFFF_FFFD: 4,294,967,294 (4G-2) bytes are to be transferred 0xFFFF_FFFE: 4,294,967,295 (4G-1) bytes are to be transferred 0xFFFF_FFFF: undefined length – all bytes until the end of Flash memory (as defined by FSIZE) are to be transferred. Continue reading indefinitely if FSIZE = 0x1F. DL[0] is stuck at 1 in dual-flash mode (DFM = 1) even when 0 is written to this bit, thus assuring that each access transfers an even number of bytes. This field has no effect when in memory-mapped mode (FMODE = 10). This field can be written only when BUSY = 0.

pub unsafe fn bits(&mut self, bits: u32) -> &mut W

Writes raw bits to the register.

Methods from Deref<Target = W<DLR_SPEC>>

pub unsafe fn bits(&mut self, bits: <REG as RegisterSpec>::Ux) -> &mut W<REG>

Writes raw bits to the register.

Trait Implementations

impl Deref for W

type Target = W<DLR_SPEC>

The resulting type after dereferencing.

fn deref(&self) -> &<W as Deref>::Target

Dereferences the value.

impl DerefMut for W

fn deref_mut(&mut self) -> &mut <W as Deref>::Target

Mutably dereferences the value.

impl From<W<DLR_SPEC>> for W

fn from(writer: W<DLR_SPEC>) -> W

Converts to this type from the input type.
