The AMCNTENSET0 characteristics are:
Enable control bits for the architected activity monitors event counters, AMEVCNTR0<n>.
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_AMUv1 is implemented. Otherwise, direct accesses to AMCNTENSET0 are RES0.
AMCNTENSET0 is a 32-bit register.

The reset behaviour of this field is:
Reserved,Activity RAZ/WI.monitor event counter enable bit forAMEVCNTR0<n>.
ThisBits field[15:N] isare reserved for additional architected activity monitor event countersRAZ/WI, whichwhere ArmN mightis define in a future version of the Activityvalue Monitors architecture.inAMCGCR.CG0NC.
Activity monitor event counter enable bit for AMEVCNTR0<n>.
AMCGCR.CG0NC identifies the number of architected activity monitor event counters. In an implementation that includes FEAT_AMUv1, the number of architected activity monitor event counters is 4.
Possible values of each bit are:
P<n> | Meaning |

0b0 | When read, means that AMEVCNTR0<n> is disabled. |
0b1 | When read, means that AMEVCNTR0<n> is enabled. |
