impl Nssr

pub const fn bsy(&self) -> bool

busy flag BSY flag indicates that a flash memory is busy by an operation (write, erase, option byte change, OBK operation). It is set at the beginning of a flash memory operation and cleared when the operation finishes, or an error occurs.

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

busy flag BSY flag indicates that a flash memory is busy by an operation (write, erase, option byte change, OBK operation). It is set at the beginning of a flash memory operation and cleared when the operation finishes, or an error occurs.

pub const fn wbne(&self) -> bool

write buffer not empty flag WBNE flag is set when the flash interface is waiting for new data to complete the write buffer. In this state, the write buffer is not empty. WBNE is reset by hardware each time the write buffer is complete or the write buffer is emptied following one of the event below: the application software forces the write operation using FW bit in FLASH_NSCR the embedded flash memory detects an error that involves data loss This bit cannot be reset by software writing 0 directly. To reset it, clear the write buffer by performing any of the above listed actions, or send the missing data.

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

write buffer not empty flag WBNE flag is set when the flash interface is waiting for new data to complete the write buffer. In this state, the write buffer is not empty. WBNE is reset by hardware each time the write buffer is complete or the write buffer is emptied following one of the event below: the application software forces the write operation using FW bit in FLASH_NSCR the embedded flash memory detects an error that involves data loss This bit cannot be reset by software writing 0 directly. To reset it, clear the write buffer by performing any of the above listed actions, or send the missing data.

pub const fn dbne(&self) -> bool

data buffer not empty flag DBNE flag is set when the flash interface is processing 6-bits ECC data in dedicated buffer. This bit cannot be set to 0 by software. The hardware resets it once the buffer is free.

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

data buffer not empty flag DBNE flag is set when the flash interface is processing 6-bits ECC data in dedicated buffer. This bit cannot be set to 0 by software. The hardware resets it once the buffer is free.

pub const fn eop(&self) -> bool

end of operation flag EOP flag is set when a operation (program/erase) completes. An interrupt is generated if the EOPIE is set to 1. It is not necessary to reset EOP before starting a new operation. EOP bit is cleared by writing 1 to CLR_EOP bit in FLASH_NSCCR register.

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

end of operation flag EOP flag is set when a operation (program/erase) completes. An interrupt is generated if the EOPIE is set to 1. It is not necessary to reset EOP before starting a new operation. EOP bit is cleared by writing 1 to CLR_EOP bit in FLASH_NSCCR register.

pub const fn wrperr(&self) -> bool

write protection error flag WRPERR flag is raised when a protection error occurs during a program operation. An interrupt is also generated if the WRPERRIE is set to 1. Writing 1 to CLR_WRPERR bit in FLASH_NSCCR register clears WRPERR.

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

write protection error flag WRPERR flag is raised when a protection error occurs during a program operation. An interrupt is also generated if the WRPERRIE is set to 1. Writing 1 to CLR_WRPERR bit in FLASH_NSCCR register clears WRPERR.

pub const fn pgserr(&self) -> bool

programming sequence error flag PGSERR flag is raised when a sequence error occurs. An interrupt is generated if the PGSERRIE bit is set to 1. Writing 1 to CLR_PGSERR bit in FLASH_NSCCR register clears PGSERR.

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

programming sequence error flag PGSERR flag is raised when a sequence error occurs. An interrupt is generated if the PGSERRIE bit is set to 1. Writing 1 to CLR_PGSERR bit in FLASH_NSCCR register clears PGSERR.

pub const fn strberr(&self) -> bool

strobe error flag STRBERR flag is raised when a strobe error occurs (when the master attempts to write several times the same byte in the write buffer). An interrupt is generated if the STRBERRIE bit is set to 1. Writing 1 to CLR_STRBERR bit in FLASH_NSCCR register clears STRBERR.

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

strobe error flag STRBERR flag is raised when a strobe error occurs (when the master attempts to write several times the same byte in the write buffer). An interrupt is generated if the STRBERRIE bit is set to 1. Writing 1 to CLR_STRBERR bit in FLASH_NSCCR register clears STRBERR.

pub const fn incerr(&self) -> bool

inconsistency error flag NSINCERR flag is raised when a inconsistency error occurs. An interrupt is generated if INCERRIE is set to 1. Writing 1 to CLR_INCERR bit in the FLASH_NSCCR register clears NSINCERR.

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

inconsistency error flag NSINCERR flag is raised when a inconsistency error occurs. An interrupt is generated if INCERRIE is set to 1. Writing 1 to CLR_INCERR bit in the FLASH_NSCCR register clears NSINCERR.

pub const fn obkerr(&self) -> bool

OBK general error flag OBKERR flag is raised when the OBK-HDPL signal from the SBS does not match the HDPL value associated with the key slot during access to the key location. Alternatively also when the ALT_SECT is unexpectedly changed while the write buffer is being filled.

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

OBK general error flag OBKERR flag is raised when the OBK-HDPL signal from the SBS does not match the HDPL value associated with the key slot during access to the key location. Alternatively also when the ALT_SECT is unexpectedly changed while the write buffer is being filled.

pub const fn obkwerr(&self) -> bool

OBK write error flag OBKWERR flag is raised when the address is not virgin on a write access to the OBK storage. Alternatively also when the OBK selector in the alternate sector is not virgin during a swap operation.

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

OBK write error flag OBKWERR flag is raised when the address is not virgin on a write access to the OBK storage. Alternatively also when the OBK selector in the alternate sector is not virgin during a swap operation.

pub const fn optchangeerr(&self) -> bool

Option byte change error flag OPTCHANGEERR flag indicates that an error occurred during an option byte change operation. When OPTCHANGEERR is set to 1, the option byte change operation did not successfully complete. An interrupt is generated when this flag is raised if the OPTCHANGEERRIE bit of FLASH_NSCR register is set to 1. Writing 1 to CLR_OPTCHANGEERR of register FLASH_NSCCR clears OPTCHANGEERR. Note: The OPTSTRT bit in FLASH_OPTCR cannot be set while OPTCHANGEERR is set.

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

Option byte change error flag OPTCHANGEERR flag indicates that an error occurred during an option byte change operation. When OPTCHANGEERR is set to 1, the option byte change operation did not successfully complete. An interrupt is generated when this flag is raised if the OPTCHANGEERRIE bit of FLASH_NSCR register is set to 1. Writing 1 to CLR_OPTCHANGEERR of register FLASH_NSCCR clears OPTCHANGEERR. Note: The OPTSTRT bit in FLASH_OPTCR cannot be set while OPTCHANGEERR is set.
