impl Seccr

pub const fn lock(&self) -> bool

configuration lock bit This bit locks the FLASH_SECCR register. The correct write sequence to FLASH_SECKEYR register unlocks this bit. If a wrong sequence is executed, or if the unlock sequence to FLASH_NSKEYR is performed twice, this bit remains locked until the next system reset. LOCK can be set by programming it to 1. When set to 1, a new unlock sequence is mandatory to unlock it. When LOCK changes from 0 to 1, the other bits of FLASH_SECCR register do not change.

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

configuration lock bit This bit locks the FLASH_SECCR register. The correct write sequence to FLASH_SECKEYR register unlocks this bit. If a wrong sequence is executed, or if the unlock sequence to FLASH_NSKEYR is performed twice, this bit remains locked until the next system reset. LOCK can be set by programming it to 1. When set to 1, a new unlock sequence is mandatory to unlock it. When LOCK changes from 0 to 1, the other bits of FLASH_SECCR register do not change.

pub const fn pg(&self) -> bool

programming control bit PG can be programmed only when LOCK is cleared to 0. PG allows programming in Bank1 and Bank2.

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

programming control bit PG can be programmed only when LOCK is cleared to 0. PG allows programming in Bank1 and Bank2.

pub const fn ser(&self) -> bool

sector erase request Setting SER bit to 1 requests a sector erase. SER can be programmed only when LOCK is cleared to 0. If BER and MER are also set, a PGSERR is raised.

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

sector erase request Setting SER bit to 1 requests a sector erase. SER can be programmed only when LOCK is cleared to 0. If BER and MER are also set, a PGSERR is raised.

pub const fn ber(&self) -> bool

erase request Setting BER bit to 1 requests a bank erase operation (user flash memory only). BER can be programmed only when LOCK is cleared to 0. If MER and SER are also set, a PGSERR is raised. Note: Write protection error is triggered when a bank erase is required and some sectors are protected.

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

erase request Setting BER bit to 1 requests a bank erase operation (user flash memory only). BER can be programmed only when LOCK is cleared to 0. If MER and SER are also set, a PGSERR is raised. Note: Write protection error is triggered when a bank erase is required and some sectors are protected.

pub const fn fw(&self) -> bool

write forcing control bit FW forces a write operation even if the write buffer is not full. In this case all bits not written are set to 1 by hardware. FW can be programmed only when LOCK is cleared to 0. The embedded flash memory resets FW when the corresponding operation has been acknowledged. Note: Using a force-write operation prevents the application from updating later the missing bits with something else than 1, because it is likely that it leads to permanent ECC error. Write forcing is effective only if the write buffer is not empty and was filled by secure access (in particular, FW does not start several write operations when the force-write operations are performed consecutively). Since there is just one write buffer, FW can force a write in bank1 or bank2.

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

write forcing control bit FW forces a write operation even if the write buffer is not full. In this case all bits not written are set to 1 by hardware. FW can be programmed only when LOCK is cleared to 0. The embedded flash memory resets FW when the corresponding operation has been acknowledged. Note: Using a force-write operation prevents the application from updating later the missing bits with something else than 1, because it is likely that it leads to permanent ECC error.

Since there is just one write buffer, FW can force a write in bank1 or bank2.

pub const fn strt(&self) -> bool

erase start control bit STRT bit is used to start a sector erase or a bank erase operation. STRT can be programmed only when LOCK is cleared to 0. STRT is reseted at the end of the operation or when an error occurs. It cannot be reset by software.

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

erase start control bit STRT bit is used to start a sector erase or a bank erase operation. STRT can be programmed only when LOCK is cleared to 0. STRT is reseted at the end of the operation or when an error occurs. It cannot be reset by software.

pub const fn mer(&self) -> bool

mass erase request Setting MER bit to 1 requests a mass erase operation (user flash memory only). MER can be programmed only when LOCK is cleared to 0. If BER or SER are also set, a PGSERR is raised. Error is triggered when a mass erase is required and some sectors are protected.

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

mass erase request Setting MER bit to 1 requests a mass erase operation (user flash memory only). MER can be programmed only when LOCK is cleared to 0. If BER or SER are also set, a PGSERR is raised. Error is triggered when a mass erase is required and some sectors are protected.
