Struct Dmactrl 

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

DMA Control. Two external DMA request channels, with ports 0-4 or Port80. Software primes the first block; DMA enable refills. The function says “up to 3 ports” but 52.3.1.9 and the register expose two DMA requests. The DMA1EN/DMA0EN tables mention action 3 for mailbox while their encoding lists reserve 3; no variant 3 is provided.

Implementations

impl Dmactrl

pub const fn dma0en(&self) -> DmactrlDma0en

DMA 0 Enable. Encodings: 0: Disabled. The DMA channel is not used.; 1: Triggers on Host Read empty (whether endpoint and a byte or mailbox and many bytes). Allows reload of memory.; 2: Triggers on Host Write complete/ready (whether endpoint and a byte, or mailbox and many bytes).

pub const fn set_dma0en(&mut self, val: DmactrlDma0en)

DMA 0 Enable. Encodings: 0: Disabled. The DMA channel is not used.; 1: Triggers on Host Read empty (whether endpoint and a byte or mailbox and many bytes). Allows reload of memory.; 2: Triggers on Host Write complete/ready (whether endpoint and a byte, or mailbox and many bytes).

pub const fn dma1en(&self) -> DmactrlDma1en

DMA 1 Enable. Encodings: 0: Disabled. The DMA channel is not used.; 1: Triggers on Host Read empty (whether endpoint and a byte or mailbox and many bytes). Allows reload of memory.; 2: Triggers on Host Write complete/ready (whether endpoint and a byte or mailbox and many bytes).

pub const fn set_dma1en(&mut self, val: DmactrlDma1en)

DMA 1 Enable. Encodings: 0: Disabled. The DMA channel is not used.; 1: Triggers on Host Read empty (whether endpoint and a byte or mailbox and many bytes). Allows reload of memory.; 2: Triggers on Host Write complete/ready (whether endpoint and a byte or mailbox and many bytes).

pub const fn dma0port(&self) -> DmactrlDma0port

DMA 0 Port

pub const fn set_dma0port(&mut self, val: DmactrlDma0port)

DMA 0 Port

pub const fn dma1port(&self) -> DmactrlDma1port

Selects port operating DMA. Encodings: 0: Port 0; 1: Port 1; 2: Port 2; 3: Port 3; 4: Port 4; 8: Port80. Used to offload the Port80 bytes (only host writes apply to Port80).

pub const fn set_dma1port(&mut self, val: DmactrlDma1port)

Selects port operating DMA. Encodings: 0: Port 0; 1: Port 1; 2: Port 2; 3: Port 3; 4: Port 4; 8: Port80. Used to offload the Port80 bytes (only host writes apply to Port80).

pub const fn cnt0(&self) -> u8

Reload Count 0

pub const fn set_cnt0(&mut self, val: u8)

Reload Count 0

pub const fn cnt1(&self) -> u8

Reload Count 1

pub const fn set_cnt1(&mut self, val: u8)

Reload Count 1

Trait Implementations

impl Clone for Dmactrl

fn clone(&self) -> Dmactrl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dmactrl

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

Formats the value using the given formatter.

impl Default for Dmactrl

fn default() -> Dmactrl

Returns the “default value” for a type.

impl PartialEq for Dmactrl

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