PMINTENCLR

Enables the generation of interrupt requests or, when FEAT_EBEP is implemented, PMU exceptions on overflows from the following counters:

Reading from this register shows which overflow interrupt requests or PMU exceptions are enabled.

Configuration

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.

Attributes

Field descriptions

C, bit [31]

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:

On a Warm reset, this field resets to an architecturally UNKNOWN value.

P<m>, bit [m], for m = 30 to 0

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:

This field reads-as-zero and ignores writes if any of the following are true:
- All of the following are true:
  - EL2 is implemented and enabled in the current Security state.
  - m >= UInt(MDCR_EL2.HPMN).
  - EL2 using AArch64.
  - Accessed at EL1.
- All of the following are true:
  - EL2 is implemented and enabled in the current Security state.
  - m >= UInt(HDCR.HPMN).
  - EL2 using AArch32.
  - Accessed at EL1.
- m >= UInt(PMCR.N).
Otherwise access to this field is W1C.

The reset behavior of this field is:

On a Warm reset, this field resets to an architecturally UNKNOWN value.
