Allows software to disable the generation of interrupt requests on overflows from the following counters:
Reading from this register shows which overflow interrupt requests are enabled.
AArch32 System register PMINTENCLR bits [31:0] are architecturally mapped to AArch64 System register PMINTENCLR_EL1[31:0].
AArch32 System register PMINTENCLR bits [31:0] are architecturally mapped to External register PMU.PMINTENCLR_EL1[31:0].
This register is present only when EL1 is capable of using AArch32 and FEAT_PMUv3 is implemented. Otherwise, direct accesses to PMINTENCLR are UNDEFINED.
PMINTENCLR is a 32-bit register.

Interrupt request or PMU exception on unsigned overflow of PMCCNTR disable. On writes, allows software to disable the interrupt request or PMU exception on unsigned overflow of PMCCNTR. On reads, returns the interrupt request or PMU exception on unsigned overflow of PMCCNTR enable status.
| C | Meaning |
|---|---|
| 0b0 |
Interrupt request or PMU exception on unsigned overflow of PMCCNTR disabled. |
| 0b1 |
Interrupt request or PMU exception on unsigned overflow of PMCCNTR enabled. |
Access to this field is W1C.
The reset behavior of this field is:
Interrupt request or PMU exception on unsigned overflow of PMEVCNTR<m> disable. On writes, allows software to disable the interrupt request or PMU exception on unsigned overflow of PMEVCNTR<m>. On reads, returns the interrupt request or PMU exception on unsigned overflow of PMEVCNTR<m> enable status.
| P<m> | Meaning |
|---|---|
| 0b0 |
Interrupt request or PMU exception on unsigned overflow of PMEVCNTR<m> disabled. |
| 0b1 |
Interrupt request or PMU exception on unsigned overflow of PMEVCNTR<m> enabled. |
Accessing this field has the following behavior:
