Struct InterruptStatusRegister 

pub struct InterruptStatusRegister(/* private fields */);

Contains the status of the interrupt signal, TZCINT, that reports access security violations or region overlap errors.

Implementations

impl InterruptStatusRegister

pub const fn overlap(&self, index: usize) -> bool

When a bit is set to 1 it indicates a violation of the overlap region configuration rules for the associated filter unit. This occurs when an access matches with two enabled regions at the same time unless the overlap is only with Region 0.

This bit is set even if the ActionRegister is set to not drive the interrupt.

When this bit is true, the interrupt status bit is also set to true.

Clear the interrupt status of the associated bit in the InterruptClearRegister to also clear this field.

pub const fn overrun(&self, index: usize) -> bool

When a bit is set to true, it indicates the occurrence of two or more region permission or region overlapping failures at the associated filter unit after the interrupt was cleared by the associated bit in the InterruptClearRegister.

This bit is set even if the ActionRegister is set to not drive the interrupt.

Clear the interrupt status of the associated bit in the InterruptClearRegister to also clear this field.

pub const fn status(&self, index: usize) -> bool

This field indicates the status of the interrupt from the corresponding filter unit as follows:

• false: Interrupt is not asserted.
• true: Interrupt is asserted and waiting to be cleared.

This bit is set even if the ActionRegister is set to not drive the interrupt output TZCINT HIGH.

Therefore, the status acts as an indicator that a region permission check failure or an overlap error has occurred at a particular filter unit.
