impl Sr

pub const fn ifem(&self) -> bool

Input FIFO empty.

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

Input FIFO empty.

pub const fn ifnf(&self) -> bool

Input FIFO not full.

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

Input FIFO not full.

pub const fn ofne(&self) -> bool

Output FIFO not empty.

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

Output FIFO not empty.

pub const fn offu(&self) -> bool

Output FIFO full.

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

Output FIFO full.

pub const fn busy(&self) -> bool

Busy bit.

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

Busy bit.

pub const fn kerf(&self) -> bool

Key error flag This read-only bit is set by hardware when key information failed to load into key registers. KERF is triggered upon any of the following errors: CRYP_KxR/LR register write does not respect the correct order (refer to Section 60.4.16: CRYP key registers for details). CRYP fails to load the key shared by SAES peripheral (KMOD = 0x2). KERF must be cleared by the application software, otherwise KEYVALID cannot be set. It can be done through IPRST bit of CRYP_CR, or when a correct key writing sequence starts.

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

Key error flag This read-only bit is set by hardware when key information failed to load into key registers. KERF is triggered upon any of the following errors: CRYP_KxR/LR register write does not respect the correct order (refer to Section 60.4.16: CRYP key registers for details). CRYP fails to load the key shared by SAES peripheral (KMOD = 0x2). KERF must be cleared by the application software, otherwise KEYVALID cannot be set. It can be done through IPRST bit of CRYP_CR, or when a correct key writing sequence starts.

pub const fn keyvalid(&self) -> bool

Key valid flag This read-only bit is set by hardware when the key of size defined by KEYSIZE is loaded in CRYP_KxR/LR key registers. The CRYPEN bit can only be set when KEYVALID is set. In normal mode when KMOD[1:0] is at zero, the key must be written in the key registers in the correct sequence, otherwise the KERF flag is set and KEYVALID remains cleared. When KMOD[1:0] is different from zero, the BUSY flag is automatically set by CRYP. When the key is loaded successfully, BUSY is cleared and KEYVALID set. Upon an error, KERF is set, BUSY cleared and KEYVALID remains cleared. If set, KERF must be cleared, otherwise KEYVALID cannot be set. For further information on key loading, refer to Section 60.4.16: CRYP key registers.

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

Key valid flag This read-only bit is set by hardware when the key of size defined by KEYSIZE is loaded in CRYP_KxR/LR key registers. The CRYPEN bit can only be set when KEYVALID is set. In normal mode when KMOD[1:0] is at zero, the key must be written in the key registers in the correct sequence, otherwise the KERF flag is set and KEYVALID remains cleared. When KMOD[1:0] is different from zero, the BUSY flag is automatically set by CRYP. When the key is loaded successfully, BUSY is cleared and KEYVALID set. Upon an error, KERF is set, BUSY cleared and KEYVALID remains cleared. If set, KERF must be cleared, otherwise KEYVALID cannot be set.
