Struct Dma

pub struct Dma { /* private fields */ }

DMA with separate read and write masters

Implementations

impl Dma

pub const unsafe fn from_ptr(ptr: *mut ()) -> Self

pub const fn as_ptr(&self) -> *mut ()

pub const fn ch(self, n: usize) -> Channel

pub const fn intr(self) -> Reg<Intr, RW>

Interrupt Status (raw)

pub const fn inte0(self) -> Reg<Inte0, RW>

Interrupt Enables for IRQ 0

pub const fn intf0(self) -> Reg<Intf0, RW>

Force Interrupts

pub const fn ints0(self) -> Reg<Ints0, RW>

Interrupt Status for IRQ 0

pub const fn inte1(self) -> Reg<Inte1, RW>

Interrupt Enables for IRQ 1

pub const fn intf1(self) -> Reg<Intf1, RW>

Force Interrupts for IRQ 1

pub const fn ints1(self) -> Reg<Ints1, RW>

Interrupt Status (masked) for IRQ 1

pub const fn timer(self, n: usize) -> Reg<Timer, RW>

Pacing (X/Y) Fractional Timer The pacing timer produces TREQ assertions at a rate set by ((X/Y) * sys_clk). This equation is evaluated every sys_clk cycles and therefore can only generate TREQs at a rate of 1 per sys_clk (i.e. permanent TREQ) or less.

pub const fn multi_chan_trigger(self) -> Reg<MultiChanTrigger, RW>

Trigger one or more channels simultaneously

pub const fn sniff_ctrl(self) -> Reg<SniffCtrl, RW>

Sniffer Control

pub const fn sniff_data(self) -> Reg<u32, RW>

Data accumulator for sniff hardware Write an initial seed value here before starting a DMA transfer on the channel indicated by SNIFF_CTRL_DMACH. The hardware will update this register each time it observes a read from the indicated channel. Once the channel completes, the final result can be read from this register.

pub const fn fifo_levels(self) -> Reg<FifoLevels, RW>

Debug RAF, WAF, TDF levels

pub const fn chan_abort(self) -> Reg<ChanAbort, RW>

Abort an in-progress transfer sequence on one or more channels

pub const fn n_channels(self) -> Reg<Nchannels, RW>

The number of channels this DMA instance is equipped with. This DMA supports up to 16 hardware channels, but can be configured with as few as one, to minimise silicon area.

Trait Implementations

impl Clone for Dma

fn clone(&self) -> Dma

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for Dma

fn eq(&self, other: &Dma) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
