Implementations§

impl RegionCfgr

pub const fn reg_en(&self) -> bool

region on-the-fly decryption enable Note: Garbage is decrypted if region context (version, key, nonce) is not valid when this bit is set.

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

region on-the-fly decryption enable Note: Garbage is decrypted if region context (version, key, nonce) is not valid when this bit is set.

pub const fn configlock(&self) -> bool

region config lock Note: This bit is set once. If this bit is set, it can only be reset to 0 if OTFDEC is reset. Setting this bit forces KEYLOCK bit to 1.

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

region config lock Note: This bit is set once. If this bit is set, it can only be reset to 0 if OTFDEC is reset. Setting this bit forces KEYLOCK bit to 1.

pub const fn keylock(&self) -> bool

region key lock Note: This bit is set once: if this bit is set, it can only be reset to 0 if the OTFDEC is reset.

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

region key lock Note: This bit is set once: if this bit is set, it can only be reset to 0 if the OTFDEC is reset.

pub const fn mode(&self) -> Mode

operating mode This bitfield selects the OTFDEC operating mode for this region: Others: Reserved When MODE ≠ 11, the standard AES encryption mode is activated. When either of the MODE bits are changed, the region key and associated CRC are zeroed.

pub fn set_mode(&mut self, val: Mode)

operating mode This bitfield selects the OTFDEC operating mode for this region: Others: Reserved When MODE ≠ 11, the standard AES encryption mode is activated. When either of the MODE bits are changed, the region key and associated CRC are zeroed.

pub const fn keycrc(&self) -> u8

region key 8-bit CRC When KEYLOCK = 0, KEYCRC bitfield is automatically computed by hardware while loading the key of this region in this exact sequence: KEYR0 then KEYR1 then KEYR2 then finally KEYR3 (all written once). A new computation starts as soon as a new valid sequence is initiated, and KEYCRC is read as zero until a valid sequence is completed. When KEYLOCK = 1, KEYCRC remains unchanged until the next reset. CRC computation is an 8-bit checksum using the standard CRC-8-CCITT algorithm X8 + X2 + X + 1 (according the convention). Source code is available in . This field is read only. Note: CRC information is updated only after the last bit of the key has been written.

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

Note: CRC information is updated only after the last bit of the key has been written.

pub const fn reg_version(&self) -> u16

region firmware version This 16-bit bitfield must be correctly initialized before the region corresponding REG_EN bit is set in OTFDEC_RxCFGR.

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

region firmware version This 16-bit bitfield must be correctly initialized before the region corresponding REG_EN bit is set in OTFDEC_RxCFGR.
