Struct rp_pac::usb_dpram::regs::EpBufferControl

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

Buffer control for both buffers of an endpoint. Fields ending in a _1 are for buffer 1. Fields ending in a _0 are for buffer 0. Buffer 1 controls are only valid if the endpoint is in double buffered mode.

Tuple Fields

0: u32

Implementations

impl EpBufferControl

pub const fn length(&self, n: usize) -> u16

The length of the data in buffer 1.

pub fn set_length(&mut self, n: usize, val: u16)

The length of the data in buffer 1.

pub const fn available(&self, n: usize) -> bool

Buffer 0 is available. This bit is set to indicate the buffer can be used by the controller. The controller clears the available bit when writing the status back.

pub fn set_available(&mut self, n: usize, val: bool)

Buffer 0 is available. This bit is set to indicate the buffer can be used by the controller. The controller clears the available bit when writing the status back.

pub const fn stall(&self) -> bool

Reply with a stall (valid for both buffers).

pub fn set_stall(&mut self, val: bool)

Reply with a stall (valid for both buffers).

pub const fn reset(&self) -> bool

Reset the buffer selector to buffer 0.

pub fn set_reset(&mut self, val: bool)

Reset the buffer selector to buffer 0.

pub const fn pid(&self, n: usize) -> bool

The data pid of buffer 0.

pub fn set_pid(&mut self, n: usize, val: bool)

The data pid of buffer 0.

pub const fn last(&self, n: usize) -> bool

Buffer 0 is the last buffer of the transfer.

pub fn set_last(&mut self, n: usize, val: bool)

Buffer 0 is the last buffer of the transfer.

pub const fn full(&self, n: usize) -> bool

Buffer 0 is full. For an IN transfer (TX to the host) the bit is set to indicate the data is valid. For an OUT transfer (RX from the host) this bit should be left as a 0. The host will set it when it has filled the buffer with data.

pub fn set_full(&mut self, n: usize, val: bool)

Buffer 0 is full. For an IN transfer (TX to the host) the bit is set to indicate the data is valid. For an OUT transfer (RX from the host) this bit should be left as a 0. The host will set it when it has filled the buffer with data.

pub const fn double_buffer_iso_offset( &self, ) -> EpBufferControlDoubleBufferIsoOffset

The number of bytes buffer 1 is offset from buffer 0 in Isochronous mode. Only valid in double buffered mode for an Isochronous endpoint. For a non Isochronous endpoint the offset is always 64 bytes.

pub fn set_double_buffer_iso_offset( &mut self, val: EpBufferControlDoubleBufferIsoOffset, )

The number of bytes buffer 1 is offset from buffer 0 in Isochronous mode. Only valid in double buffered mode for an Isochronous endpoint. For a non Isochronous endpoint the offset is always 64 bytes.

Trait Implementations

impl Clone for EpBufferControl

fn clone(&self) -> EpBufferControl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for EpBufferControl

fn default() -> EpBufferControl

Returns the “default value” for a type.

impl PartialEq for EpBufferControl

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