Variants

EACHBLOCK = 0

at block level (when CH[x].BR1.BNDT[15:0] = 0): the complete (and the half) transfer event is generated at the (respectively half of the) end of a block.

EACH2DBLOCK = 1

channel x = 0 to 11, same as 00; channel x=12 to 15, at 2D/repeated block level (when CH[x].BR1.BRC[10:0] = 0 and CH[x].BR1.BNDT[15:0] = 0), the complete (and the half) transfer event is generated at the end (respectively half of the end) of the 2D/repeated block.

EACHLINKEDLISTITEM = 2

at LLI level: the complete transfer event is generated at the end of the LLI transfer, including the update of the LLI if any. The half transfer event is generated at the half of the LLI data transfer (the LLI data transfer being a block transfer or a 2D/repeated block transfer for channel x = 12 to 15), if any data transfer.

LASTLINKEDLISTITEM = 3

at channel level: the complete transfer event is generated at the end of the last LLI transfer. The half transfer event is generated at the half of the data transfer of the last LLI. The last LLI updates the link address CH[x].LLR.LA[15:2] to zero and clears all the CH[x].LLR update bits (UT1, UT2, UB1, USA, UDA and ULL, plus UT3 and UB2 if present). If the channel transfer is continuous/infinite, no event is generated.

Implementations

impl Tcem

pub const fn from_bits(val: u8) -> Tcem

pub const fn to_bits(self) -> u8

Trait Implementations

impl Clone for Tcem

fn clone(&self) -> Tcem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Tcem> for u8

fn from(val: Tcem) -> u8

Converts to this type from the input type.

impl From<u8> for Tcem

fn from(val: u8) -> Tcem

Converts to this type from the input type.

impl Ord for Tcem

fn cmp(&self, other: &Tcem) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Tcem

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

impl PartialOrd for Tcem

fn partial_cmp(&self, other: &Tcem) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
