impl Optcr

pub const fn optlock(&self) -> bool

Options lock When this bit is set write to all other bits in this register, and write to OTP words, option bytes and option bytes keys control registers, are ignored. Clearing this bit requires the correct write sequence to FLASH_OPTKEYR register (see this register for details). If a wrong sequence is executed, or the unlock sequence is performed twice, this bit remains locked until next system reset. During the write access to set LOCK bit from 0 to 1, it is possible to change the other bits of this register.

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

Options lock When this bit is set write to all other bits in this register, and write to OTP words, option bytes and option bytes keys control registers, are ignored. Clearing this bit requires the correct write sequence to FLASH_OPTKEYR register (see this register for details). If a wrong sequence is executed, or the unlock sequence is performed twice, this bit remains locked until next system reset. During the write access to set LOCK bit from 0 to 1, it is possible to change the other bits of this register.

pub const fn pg_opt(&self) -> bool

Program options.

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

Program options.

pub const fn kveie(&self) -> bool

Key valid error interrupt enable bit This bit controls if an interrupt has to be generated when KVEF is set in FLASH_OPTISR.

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

Key valid error interrupt enable bit This bit controls if an interrupt has to be generated when KVEF is set in FLASH_OPTISR.

pub const fn kteie(&self) -> bool

Key transfer error interrupt enable bit This bit controls if an interrupt has to be generated when KTEF is set in FLASH_OPTISR.

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

Key transfer error interrupt enable bit This bit controls if an interrupt has to be generated when KTEF is set in FLASH_OPTISR.

pub const fn opterrie(&self) -> bool

Option byte change error interrupt enable bit This bit controls if an interrupt has to be generated when an error occurs during an option byte change.

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

Option byte change error interrupt enable bit This bit controls if an interrupt has to be generated when an error occurs during an option byte change.
