AMCNTENSET0, Activity Monitors Count Enable Set Register 0

The AMCNTENSET0 characteristics are:

Purpose

Enable control bits for the architected activity monitors event counters, AMEVCNTR0<n>.

Configuration

External register AMCNTENSET0 bits [31:0] are architecturally mapped to AArch64 System register AMCNTENSET0_EL0[31:0] .

External register AMCNTENSET0 bits [31:0] are architecturally mapped to AArch32 System register AMCNTENSET0[31:0] .

The power domain of AMCNTENSET0 is IMPLEMENTATION DEFINED.

This register is present only when FEAT_AMUv1AMUv1 is implemented. Otherwise, direct accesses to AMCNTENSET0 are RES0.

Attributes

AMCNTENSET0 is a 32-bit register.

Field descriptions

The AMCNTENSET0 bit assignments are:

313029282726252423222120191817161514131211109876543210
P<n>, bit [n]

P<n>, bit [n], for n = 0 to 31

Activity monitor event counter enable bit for AMEVCNTR0<n>.

Bits [31:N] are RAZ/WI. N is the value in AMCGCR.CG0NC.

Possible values of each bit are:

P<n>Meaning
0b0

When read, means that AMEVCNTR0<n> is disabled. When written, has no effect.

0b1

When read, means that AMEVCNTR0<n> is enabled. When written, enables AMEVCNTR0<n>.

On a Cold reset, this field resets to 0.

Accessing the AMCNTENSET0

AMCNTENSET0 can be accessed through the memory-mapped interfaces:

ComponentOffsetInstance
AMU0xC00AMCNTENSET0

Accesses on this interface are RO.
