Captures the address of the instruction generating a PMU exception.
This register is present only when FEAT_SEBEP is implemented. Otherwise, direct accesses to PMIAR_EL1 are UNDEFINED.
PMIAR_EL1 is a 64-bit register.

Instruction virtual address.
For writes to PMIAR_EL1, PMIAR_EL1.ADDRESS[63:P] is RESS. P is defined as:
56, when FEAT_LVA3 is implemented.
52, when FEAT_LVA is implemented.
48, otherwise.
PMIAR_EL1.ADDRESS[1:0] is RES0.
The reset behavior of this field is:
