Description

Security configuration for IRQ 2. Control whether the IRQ permits configuration by Non-secure/Unprivileged contexts, and whether it can observe Secure/Privileged channel interrupt flags.

Fields

P

Privileged IRQ. If 1, this IRQ’s control registers can only be accessed from a Privileged context.

If 0, this IRQ’s control registers can be accessed from an Unprivileged context, but Privileged channels (as per SECCFG_CHx) are masked from the IRQ status, and this IRQ’s registers can not be used to acknowledge the channel interrupts of Privileged channels.

S

Secure IRQ. If 1, this IRQ’s control registers can only be accessed from a Secure context.

If 0, this IRQ’s control registers can be accessed from a Non-secure context, but Secure channels (as per SECCFG_CHx) are masked from the IRQ status, and this IRQ’s registers can not be used to acknowledge the channel interrupts of Secure channels.
