Implementations

impl ChTr3

pub const fn sao(&self) -> u16

source address offset increment. The source address, pointed by CH[x].SAR, is incremented or decremented (depending on CH[x].BR1.SDEC) by this offset SAO[12:0] for each programmed source burst. This offset is not including and is added to the programmed burst size when the completed burst is addressed in incremented mode (CH[x].TR1.SINC = 1). Note: A source address offset must be aligned with the programmed data width of a source burst (SAO[2:0] versus CH[x].TR1.SDW_LOG2[1:0]). Else a user setting error is reported and none transfer is issued. When the source block size is not a multiple of the destination burst size and is a multiple of the source data width, then the last programmed source burst is not completed and is internally shorten to match the block size. In this case, the additional CH[x].TR3.SAO[12:0] is not applied.

pub fn set_sao(&mut self, val: u16)

source address offset increment. The source address, pointed by CH[x].SAR, is incremented or decremented (depending on CH[x].BR1.SDEC) by this offset SAO[12:0] for each programmed source burst. This offset is not including and is added to the programmed burst size when the completed burst is addressed in incremented mode (CH[x].TR1.SINC = 1). Note: A source address offset must be aligned with the programmed data width of a source burst (SAO[2:0] versus CH[x].TR1.SDW_LOG2[1:0]). Else a user setting error is reported and none transfer is issued.

In this case, the additional CH[x].TR3.SAO[12:0] is not applied.

pub const fn dao(&self) -> u16

destination address offset increment. The destination address, pointed by CH[x].DAR, is incremented or decremented (depending on CH[x].BR1.DDEC) by this offset DAO[12:0] for each programmed destination burst. This offset is not including and is added to the programmed burst size when the completed burst is addressed in incremented mode (CH[x].TR1.DINC = 1). Note: A destination address offset must be aligned with the programmed data width of a destination burst (DAO[2:0] versus CH[x].TR1.DDW[1:0]). Else, a user setting error is reported and no transfer is issued.

pub fn set_dao(&mut self, val: u16)

destination address offset increment. The destination address, pointed by CH[x].DAR, is incremented or decremented (depending on CH[x].BR1.DDEC) by this offset DAO[12:0] for each programmed destination burst. This offset is not including and is added to the programmed burst size when the completed burst is addressed in incremented mode (CH[x].TR1.DINC = 1). Note: A destination address offset must be aligned with the programmed data width of a destination burst (DAO[2:0] versus CH[x].TR1.DDW[1:0]). Else, a user setting error is reported and no transfer is issued.

Trait Implementations

impl Clone for ChTr3

fn clone(&self) -> ChTr3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for ChTr3

fn default() -> ChTr3

Returns the “default value” for a type.

impl PartialEq for ChTr3

fn eq(&self, other: &ChTr3) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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