impl Seccfgr

pub const fn bkprwsec(&self) -> u8

Backup registers read/write protection offset. Protection zone 1 is defined for backup registers from BKP0R to BKPxR (x = BKPRWSEC-1, from 0 to 128). if TZEN=1, these backup registers can be read and written only with secure access. If TZEN=0: the protection zone 1 can be read and written with non-secure access. If BKPRWSEC = 0: there is no protection zone 1. If BKPRWPRIV is set, BKPRWSEC[7:0] can be written only in privileged mode.

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

Backup registers read/write protection offset. Protection zone 1 is defined for backup registers from BKP0R to BKPxR (x = BKPRWSEC-1, from 0 to 128). if TZEN=1, these backup registers can be read and written only with secure access. If TZEN=0: the protection zone 1 can be read and written with non-secure access. If BKPRWSEC = 0: there is no protection zone 1. If BKPRWPRIV is set, BKPRWSEC[7:0] can be written only in privileged mode.

pub const fn cnt1sec(&self) -> bool

Monotonic counter 1 secure protection

pub fn set_cnt1sec(&mut self, val: bool)

Monotonic counter 1 secure protection

pub const fn bkpwsec(&self) -> u8

Backup registers write protection offset. Protection zone 2 is defined for backup registers from BKPyR (y = BKPRWSEC, from 0 to 128) to BKPzR (z = BKPWSEC-1, from 0 to 128, BKPWSECBKPRWSEC): if TZEN=1, these backup registers can be written only with secure access. They can be read with secure or non-secure access. Protection zone 3 defined for backup registers from BKPtR (t = BKPWSEC, from 0 to 127). They can be read or written with secure or non-secure access. If TZEN=0: the protection zone 2 can be read and written with non-secure access. If BKPWSEC = 0 or if BKPWSEC BKPRWSEC: there is no protection zone 2. If BKPWPRIV is set, BKPRWSEC[7:0] can be written only in privileged mode.

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

Backup registers write protection offset. Protection zone 2 is defined for backup registers from BKPyR (y = BKPRWSEC, from 0 to 128) to BKPzR (z = BKPWSEC-1, from 0 to 128, BKPWSECBKPRWSEC): if TZEN=1, these backup registers can be written only with secure access. They can be read with secure or non-secure access. Protection zone 3 defined for backup registers from BKPtR (t = BKPWSEC, from 0 to 127). They can be read or written with secure or non-secure access. If TZEN=0: the protection zone 2 can be read and written with non-secure access. If BKPWSEC = 0 or if BKPWSEC BKPRWSEC: there is no protection zone 2. If BKPWPRIV is set, BKPRWSEC[7:0] can be written only in privileged mode.

pub const fn bhklock(&self) -> bool

Boot hardware key lock. This bit can be read and can only be written to 1 by software. It is cleared by hardware together with the backup registers following a tamper detection event or when the readout protection (RDP) is disabled.

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

Boot hardware key lock. This bit can be read and can only be written to 1 by software. It is cleared by hardware together with the backup registers following a tamper detection event or when the readout protection (RDP) is disabled.
