impl Nsobkcfgr

pub const fn lock(&self) -> bool

OBKCFGR lock option configuration bit This bit locks the FLASH_NSOBKCFGR register. The correct write sequence to FLASH_NSOBKKEYR register unlocks this bit. If a wrong sequence is executed, or if the unlock sequence to FLASH_NSOBKKEYR 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_NSCR register do not change.

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

OBKCFGR lock option configuration bit This bit locks the FLASH_NSOBKCFGR register. The correct write sequence to FLASH_NSOBKKEYR register unlocks this bit. If a wrong sequence is executed, or if the unlock sequence to FLASH_NSOBKKEYR 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_NSCR register do not change.

pub const fn swap_sect_req(&self) -> bool

OBK swap sector request bit When set, all the OBKs which have not been updated in the alternate sector is copied from current sector to alternate one. The SWAP_OFFSET value must be a certain minimum value in order for the swap to be launched in OBK-HDPL ≠ 0. Minimum value is 16 for OBK-HDPL = 1, 144 for OBK-HDPL = 2 and 192 for OBK-HDPL = 3.

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

OBK swap sector request bit When set, all the OBKs which have not been updated in the alternate sector is copied from current sector to alternate one. The SWAP_OFFSET value must be a certain minimum value in order for the swap to be launched in OBK-HDPL ≠ 0. Minimum value is 16 for OBK-HDPL = 1, 144 for OBK-HDPL = 2 and 192 for OBK-HDPL = 3.

pub const fn alt_sect(&self) -> bool

alternate sector bit This bit must not change while filling the write buffer, otherwise an error (OBKERR) is generated

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

alternate sector bit This bit must not change while filling the write buffer, otherwise an error (OBKERR) is generated

pub const fn alt_sect_erase(&self) -> bool

alternate sector erase bit When ALT_SECT bit is set, use this bit to generate an erase command for the OBK alternate sector. It is set only by Software and cleared when the OBK swap operation is completed or an error occurs (PGSERR). It is reseted at the same time as BUSY bit.

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

alternate sector erase bit When ALT_SECT bit is set, use this bit to generate an erase command for the OBK alternate sector. It is set only by Software and cleared when the OBK swap operation is completed or an error occurs (PGSERR). It is reseted at the same time as BUSY bit.

pub const fn swap_offset(&self) -> u16

Key index (offset /16 bits) pointing for next swap. 0x01 means that only the first OBK data (128 bits) is copied from current to alternate OBK sector 0x02 means that the two first OBK data is copied … …

pub fn set_swap_offset(&mut self, val: u16)

Key index (offset /16 bits) pointing for next swap. 0x01 means that only the first OBK data (128 bits) is copied from current to alternate OBK sector 0x02 means that the two first OBK data is copied … …
