Appendix B: Register Details
Register reg2_int_mask_status Details
Register (L2Cpl310) reg2_int_raw_status
Description This register is a read-only.It returns the masked interrupt status. This
register can be accessed by secure and non-secure operations. The register
gives an AND function of the raw interrupt status with the values of the
interrupt mask register. All the bits are cleared by a reset. A write to this register is
ignored. Bits read can be HIGH or LOW:
HIGH If the bits read HIGH, they reflect the status of the input lines triggering an
interrupt.
LOW If the bits read LOW, either no interrupt has been
generated, or the interrupt is masked.

Description The Raw Interrupt Status Register enables the interrupt status that excludes the
masking logic.
Bits read can be HIGH or LOW:
HIGH If the bits read HIGH, they reflect the status of the input lines triggering an
interrupt.
LOW If the bits read LOW, no interrupt has been generated.
