Enables the generation of interrupt requests on overflows from the Cycle Count Register, PMU.PMCCNTR_EL0, and the event counters PMU.PMEVCNTR<n>_EL0.
External register PMINTEN bits [63:0] are architecturally mapped to AArch64 System register PMINTENSET_EL1[63:0].
External register PMINTEN bits [63:0] are architecturally mapped to AArch64 System register PMINTENCLR_EL1[63:0].
External register PMINTEN bits [31:0] are architecturally mapped to AArch32 System register PMINTENCLR[31:0].
External register PMINTEN bits [31:0] are architecturally mapped to AArch32 System register PMINTENSET[31:0].
This register is present only when FEAT_PMUv3_EXT64 is implemented. Otherwise, direct accesses to PMINTEN are RES0.
PMINTEN is a 64-bit register.
This register is part of the PMU block.
