impl Cr

pub const fn pg(&self) -> bool

Flash memory programming enable

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

Flash memory programming enable

pub const fn per(&self) -> bool

Page erase enable

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

Page erase enable

pub const fn mer1(&self) -> bool

Mass erase When set, this bit triggers the mass erase, that is, all user pages.

pub fn set_mer1(&mut self, val: bool)

Mass erase When set, this bit triggers the mass erase, that is, all user pages.

pub const fn pnb(&self) -> u8

Page number selection These bits select the page to erase: … Note: Values corresponding to addresses outside the main memory are not allowed.

pub fn set_pnb(&mut self, val: u8)

Page number selection These bits select the page to erase: … Note: Values corresponding to addresses outside the main memory are not allowed.

pub const fn strt(&self) -> bool

Start erase operation This bit triggers an erase operation when set. This bit is possible to set only by software and to clear only by hardware. The hardware clears it when one of BSY1 and BSY2 flags in the FLASH_SR register transits to zero.

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

Start erase operation This bit triggers an erase operation when set. This bit is possible to set only by software and to clear only by hardware. The hardware clears it when one of BSY1 and BSY2 flags in the FLASH_SR register transits to zero.

pub const fn optstrt(&self) -> bool

Start of modification of option bytes This bit triggers an options operation when set. This bit is set only by software, and is cleared when the BSY1 bit is cleared in FLASH_SR.

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

Start of modification of option bytes This bit triggers an options operation when set. This bit is set only by software, and is cleared when the BSY1 bit is cleared in FLASH_SR.

pub const fn fstpg(&self) -> bool

Fast programming enable

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

Fast programming enable

pub const fn eopie(&self) -> bool

End-of-operation interrupt enable This bit enables the interrupt generation upon setting the EOP flag in the FLASH_SR register.

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

End-of-operation interrupt enable This bit enables the interrupt generation upon setting the EOP flag in the FLASH_SR register.

pub const fn errie(&self) -> bool

Error interrupt enable This bit enables the interrupt generation upon setting the OPERR flag in the FLASH_SR register.

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

Error interrupt enable This bit enables the interrupt generation upon setting the OPERR flag in the FLASH_SR register.

pub const fn rderrie(&self) -> bool

PCROP read error interrupt enable This bit enables the interrupt generation upon setting the RDERR flag in the FLASH_SR register.

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

PCROP read error interrupt enable This bit enables the interrupt generation upon setting the RDERR flag in the FLASH_SR register.

pub const fn obl_launch(&self) -> bool

Option byte load launch When set, this bit triggers the load of option bytes into option registers. It is automatically cleared upon the completion of the load. The high state of the bit indicates pending option byte load. The bit cannot be cleared by software. It cannot be written as long as OPTLOCK is set.

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

Option byte load launch When set, this bit triggers the load of option bytes into option registers. It is automatically cleared upon the completion of the load. The high state of the bit indicates pending option byte load. The bit cannot be cleared by software. It cannot be written as long as OPTLOCK is set.

pub const fn sec_prot(&self) -> bool

Securable memory area protection enable This bit enables the protection on securable area, provided that a non-null securable memory area size (SEC_SIZE[4:0]) is defined in option bytes. This bit is possible to set only by software and to clear only through a system reset.

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

Securable memory area protection enable This bit enables the protection on securable area, provided that a non-null securable memory area size (SEC_SIZE[4:0]) is defined in option bytes. This bit is possible to set only by software and to clear only through a system reset.

pub const fn optlock(&self) -> bool

Options Lock This bit is set only. When set, all bits concerning user option in FLASH_CR register and so option page are locked. This bit is cleared by hardware after detecting the unlock sequence. The LOCK bit must be cleared before doing the unlock sequence for OPTLOCK bit. In case of an unsuccessful unlock operation, this bit remains set until the next reset.

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

Options Lock This bit is set only. When set, all bits concerning user option in FLASH_CR register and so option page are locked. This bit is cleared by hardware after detecting the unlock sequence. The LOCK bit must be cleared before doing the unlock sequence for OPTLOCK bit. In case of an unsuccessful unlock operation, this bit remains set until the next reset.

pub const fn lock(&self) -> bool

FLASH_CR Lock This bit is set only. When set, the FLASH_CR register is locked. It is cleared by hardware after detecting the unlock sequence. In case of an unsuccessful unlock operation, this bit remains set until the next system reset.

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

FLASH_CR Lock This bit is set only. When set, the FLASH_CR register is locked. It is cleared by hardware after detecting the unlock sequence. In case of an unsuccessful unlock operation, this bit remains set until the next system reset.
