impl Isr

pub const fn seif(&self) -> bool

Security error interrupt flag status This bit is set by hardware and read only by application. This bit is set when at least one security error has been detected. This bit is cleared when application sets in OTFDEC_ICR the corresponding bit to 1.

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

Security error interrupt flag status This bit is set by hardware and read only by application. This bit is set when at least one security error has been detected. This bit is cleared when application sets in OTFDEC_ICR the corresponding bit to 1.

pub const fn xoneif(&self) -> bool

Execute-only execute-never error interrupt flag status This bit is set by hardware and read only by application. This bit is set when a read access and not an instruction fetch is detected on any encrypted region with MODE bits set to 11. Lastly, XONEIF is also set when an execute access is detected while encryption mode is enabled. This bit is cleared when application sets in OTFDEC_ICR the corresponding bit to 1.

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

Execute-only execute-never error interrupt flag status This bit is set by hardware and read only by application. This bit is set when a read access and not an instruction fetch is detected on any encrypted region with MODE bits set to 11. Lastly, XONEIF is also set when an execute access is detected while encryption mode is enabled. This bit is cleared when application sets in OTFDEC_ICR the corresponding bit to 1.

pub const fn keif(&self) -> bool

Key error interrupt flag status This bit is set by hardware and read only by application. The bit is set when a read access occurs on an encrypted region, while its key registers is null or not properly initialized (KEYCRC = 0x0). This bit is cleared when the application sets in OTFDEC_ICR the corresponding bit to 1. After KEIF is set any subsequent read to the region with bad key registers returns a zeroed value. This state remains until those key registers are properly initialized (KEYCRC not zero).

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

Key error interrupt flag status This bit is set by hardware and read only by application. The bit is set when a read access occurs on an encrypted region, while its key registers is null or not properly initialized (KEYCRC = 0x0). This bit is cleared when the application sets in OTFDEC_ICR the corresponding bit to 1. After KEIF is set any subsequent read to the region with bad key registers returns a zeroed value. This state remains until those key registers are properly initialized (KEYCRC not zero).
