Enum rp2040_pac::dma::ch::ch_al1_ctrl::RING_SIZE_A

#[repr(u8)]
pub enum RING_SIZE_A {
    RING_NONE = 0,
}

Size of address wrap region. If 0, don’t wrap. For values n > 0, only the lower n bits of the address will change. This wraps the address on a (1 << n) byte boundary, facilitating access to naturally-aligned ring buffers.

Ring sizes between 2 and 32768 bytes are possible. This can apply to either read or write addresses, based on value of RING_SEL.

Value on reset: 0

RING_NONE = 0

Trait Implementations

impl Clone for RING_SIZE_A

fn clone(&self) -> RING_SIZE_A

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RING_SIZE_A

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

Formats the value using the given formatter.

impl FieldSpec for RING_SIZE_A

type Ux = u8

Raw field type (u8, u16, u32, …).

impl From<RING_SIZE_A> for u8

fn from(variant: RING_SIZE_A) -> Self

Converts to this type from the input type.

impl PartialEq for RING_SIZE_A

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