impl Cr

pub const fn en(&self) -> bool

Enable This bit enables the OCTOSPI. Note: The DMA request can be aborted without having received the ACK in case this EN bit is cleared during the operation. In case. this bit is set to 0 during a DMA transfer, the REQ signal to DMA returns to inactive state without waiting for the ACK signal from DMA to be active.

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

Enable This bit enables the OCTOSPI. Note: The DMA request can be aborted without having received the ACK in case this EN bit is cleared during the operation. In case. this bit is set to 0 during a DMA transfer, the REQ signal to DMA returns to inactive state without waiting for the ACK signal from DMA to be active.

pub const fn abort(&self) -> bool

Abort request. This bit aborts the ongoing command sequence. It is automatically reset once the abort is completed. This bit stops the current transfer. Note: This bit is always read as 0.

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

Abort request. This bit aborts the ongoing command sequence. It is automatically reset once the abort is completed. This bit stops the current transfer. Note: This bit is always read as 0.

pub const fn dmaen(&self) -> bool

DMA enable In Indirect mode, the DMA can be used to input or output data via DR. DMA transfers are initiated when FTF is set. Note: Resetting the DMAEN bit while a DMA transfer is ongoing, breaks the handshake with the DMA. Do not write. this bit during DMA operation.

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

DMA enable In Indirect mode, the DMA can be used to input or output data via DR. DMA transfers are initiated when FTF is set. Note: Resetting the DMAEN bit while a DMA transfer is ongoing, breaks the handshake with the DMA. Do not write. this bit during DMA operation.

pub const fn tcen(&self) -> bool

Timeout counter enable. This bit is valid only when the Memory-mapped mode (FMODE[1:0] = 11) is selected. This bit enables the timeout counter.

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

Timeout counter enable. This bit is valid only when the Memory-mapped mode (FMODE[1:0] = 11) is selected. This bit enables the timeout counter.

pub const fn dmm(&self) -> bool

Dual-memory configuration. This bit activates the dual-memory configuration, where two external devices are used simultaneously to double the throughput and the capacity

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

Dual-memory configuration. This bit activates the dual-memory configuration, where two external devices are used simultaneously to double the throughput and the capacity

pub const fn fsel(&self) -> FlashSelect

Flash select. This bit selects the Flash memory to be addressed in Single-, Dual-, Quad-SPI mode in single-memory configuration (when DMM = 0). This bit is ignored when DMM = 1 or when Octal-SPI mode is selected.

pub fn set_fsel(&mut self, val: FlashSelect)

Flash select. This bit selects the Flash memory to be addressed in Single-, Dual-, Quad-SPI mode in single-memory configuration (when DMM = 0). This bit is ignored when DMM = 1 or when Octal-SPI mode is selected.

pub const fn fthres(&self) -> Threshold

FIFO threshold level. This field defines, in Indirect mode, the threshold number of bytes in the FIFO that causes the FIFO threshold flag FTF in SR, to be set. … Note: If DMAEN = 1, the DMA controller for the corresponding channel must be disabled before changing the FTHRES[4:0] value.

pub fn set_fthres(&mut self, val: Threshold)

FIFO threshold level. This field defines, in Indirect mode, the threshold number of bytes in the FIFO that causes the FIFO threshold flag FTF in SR, to be set. … Note: If DMAEN = 1, the DMA controller for the corresponding channel must be disabled before changing the FTHRES[4:0] value.

pub const fn teie(&self) -> bool

Transfer error interrupt enable. This bit enables the transfer error interrupt.

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

Transfer error interrupt enable. This bit enables the transfer error interrupt.

pub const fn tcie(&self) -> bool

Transfer complete interrupt enable. This bit enables the transfer complete interrupt.

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

Transfer complete interrupt enable. This bit enables the transfer complete interrupt.

pub const fn ftie(&self) -> bool

FIFO threshold interrupt enable. This bit enables the FIFO threshold interrupt.

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

FIFO threshold interrupt enable. This bit enables the FIFO threshold interrupt.

pub const fn smie(&self) -> bool

Status match interrupt enable. This bit enables the status match interrupt.

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

Status match interrupt enable. This bit enables the status match interrupt.

pub const fn toie(&self) -> bool

Timeout interrupt enable. This bit enables the timeout interrupt.

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

Timeout interrupt enable. This bit enables the timeout interrupt.

pub const fn apms(&self) -> bool

Automatic status-polling mode stop. This bit determines if the Automatic status-polling mode is stopped after a match.

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

Automatic status-polling mode stop. This bit determines if the Automatic status-polling mode is stopped after a match.

pub const fn pmm(&self) -> MatchMode

Polling match mode. This bit indicates which method must be used to determine a match during the Automatic status-polling mode.

pub fn set_pmm(&mut self, val: MatchMode)

Polling match mode. This bit indicates which method must be used to determine a match during the Automatic status-polling mode.

pub const fn fmode(&self) -> FunctionalMode

Functional mode. This field defines the OCTOSPI functional mode of operation. If DMAEN = 1 already, then the DMA controller for the corresponding channel must be disabled before changing the FMODE[1:0] value. If FMODE[1:0] and FTHRES[4:0] are wrongly updated while DMAEN = 1, the DMA request signal automatically goes to inactive state.

pub fn set_fmode(&mut self, val: FunctionalMode)

Functional mode. This field defines the OCTOSPI functional mode of operation. If DMAEN = 1 already, then the DMA controller for the corresponding channel must be disabled before changing the FMODE[1:0] value. If FMODE[1:0] and FTHRES[4:0] are wrongly updated while DMAEN = 1, the DMA request signal automatically goes to inactive state.
