impl ChSr

pub const fn idlef(&self) -> bool

idle flag. This idle flag is de-asserted by hardware when the channel is enabled (CH[x].CR.EN = 1) with a valid channel configuration (no USEF to be immediately reported). This idle flag is asserted after hard reset or by hardware when the channel is back in idle state (in suspended or disabled state).

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

idle flag. This idle flag is de-asserted by hardware when the channel is enabled (CH[x].CR.EN = 1) with a valid channel configuration (no USEF to be immediately reported). This idle flag is asserted after hard reset or by hardware when the channel is back in idle state (in suspended or disabled state).

pub const fn tcf(&self) -> bool

transfer complete flag. A transfer complete event is either a block transfer complete, a 2D/repeated block transfer complete, a LLI transfer complete including the upload of the next LLI if any, or the full linked-list completion, depending on the transfer complete event mode (CH[x].TR2.TCEM[1:0]).

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

transfer complete flag. A transfer complete event is either a block transfer complete, a 2D/repeated block transfer complete, a LLI transfer complete including the upload of the next LLI if any, or the full linked-list completion, depending on the transfer complete event mode (CH[x].TR2.TCEM[1:0]).

pub const fn htf(&self) -> bool

half transfer flag. An half transfer event is either an half block transfer or an half 2D/repeated block transfer, depending on the transfer complete event mode (CH[x].TR2.TCEM[1:0]). An half block transfer occurs when half of the bytes of the source block size (rounded up integer of CH[x].BR1.BNDT[15:0]/2) has been transferred to the destination. An half 2D/repeated block transfer occurs when half of the repeated blocks (rounded up integer of (CH[x].BR1.BRC[10:0]+1)/2)) has been transferred to the destination.

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

half transfer flag. An half transfer event is either an half block transfer or an half 2D/repeated block transfer, depending on the transfer complete event mode (CH[x].TR2.TCEM[1:0]). An half block transfer occurs when half of the bytes of the source block size (rounded up integer of CH[x].BR1.BNDT[15:0]/2) has been transferred to the destination. An half 2D/repeated block transfer occurs when half of the repeated blocks (rounded up integer of (CH[x].BR1.BRC[10:0]+1)/2)) has been transferred to the destination.

pub const fn dtef(&self) -> bool

data transfer error flag

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

data transfer error flag

pub const fn ulef(&self) -> bool

update link transfer error flag

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

update link transfer error flag

pub const fn usef(&self) -> bool

user setting error flag

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

user setting error flag

pub const fn suspf(&self) -> bool

completed suspension flag

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

completed suspension flag

pub const fn tof(&self) -> bool

trigger overrun flag

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

trigger overrun flag

pub const fn fifol(&self) -> u8

monitored FIFO level. Number of available write beats in the FIFO, in units of the programmed destination data width (see CH[x].TR1.DDW[1:0], in units of bytes, half-words, or words). Note: After having suspended an active transfer, the user may need to read FIFOL[7:0], additionally to CH[x].BR1.BDNT[15:0] and CH[x].BR1.BRC[10:0], to know how many data have been transferred to the destination. Before reading, the user may wait for the transfer to be suspended (CH[x].SR.SUSPF = 1).

pub fn set_fifol(&mut self, val: u8)

monitored FIFO level. Number of available write beats in the FIFO, in units of the programmed destination data width (see CH[x].TR1.DDW[1:0], in units of bytes, half-words, or words). Note: After having suspended an active transfer, the user may need to read FIFOL[7:0], additionally to CH[x].BR1.BDNT[15:0] and CH[x].BR1.BRC[10:0], to know how many data have been transferred to the destination.
