The PMAUTHSTATUS characteristics are:
Provides information about the state of the IMPLEMENTATION DEFINED authentication interface for Performance Monitors.
This register is present only when FEAT_PMUv3_EXT is implemented. Otherwise, direct accesses to PMAUTHSTATUS are RES0.
If FEAT_DoPD is implemented, this register is in the Core power domain. If FEAT_DoPD is not implemented, this register is in the Debug power domain.
This register is OPTIONAL, and is required for CoreSight compliance. Arm recommends that this register is implemented.
PMAUTHSTATUS is a 32-bit register.
This register is part of the PMU block.
