Implementations

impl DmaCh0RxControl2

pub const fn rdrl(&self) -> u16

Receive Descriptor Ring Length. This register sets the maximum number of Rx descriptors in the circular descriptor ring. The maximum number of descriptors is limited to 1K descriptors. For example, You can program any value up to 0x3FF in this field. This field is 10 bits wide, if you program 0x3FF, you can have 1024 descriptors. If you want to have 10 descriptors, program it to a value of 0x9.

pub const fn set_rdrl(&mut self, val: u16)

Receive Descriptor Ring Length. This register sets the maximum number of Rx descriptors in the circular descriptor ring. The maximum number of descriptors is limited to 1K descriptors. For example, You can program any value up to 0x3FF in this field. This field is 10 bits wide, if you program 0x3FF, you can have 1024 descriptors. If you want to have 10 descriptors, program it to a value of 0x9.

pub const fn arbs(&self) -> u8

Alternate Receive Buffer Size. Indicates size in bytes for Buffer 1 when ARBS is programmed to a non-zero value (when split header feature is not enabled). When split header feature is enabled, ARBS indicates the buffer size for header data. The maximum alternate buffer is limited to 1020 bytes. When ARBS=0, Rx Buffer1 and Rx Buffer2 sizes are based on RBSZ field of DMA_CH0_Rx_Control. Width of ARBS field is 8 bits.

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

Alternate Receive Buffer Size. Indicates size in bytes for Buffer 1 when ARBS is programmed to a non-zero value (when split header feature is not enabled). When split header feature is enabled, ARBS indicates the buffer size for header data. The maximum alternate buffer is limited to 1020 bytes. When ARBS=0, Rx Buffer1 and Rx Buffer2 sizes are based on RBSZ field of DMA_CH0_Rx_Control. Width of ARBS field is 8 bits.

Trait Implementations

impl Clone for DmaCh0RxControl2

fn clone(&self) -> DmaCh0RxControl2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DmaCh0RxControl2

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

Formats the value using the given formatter.

impl Default for DmaCh0RxControl2

fn default() -> DmaCh0RxControl2

Returns the “default value” for a type.

impl PartialEq for DmaCh0RxControl2

fn eq(&self, other: &DmaCh0RxControl2) -> 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.
