Provides information on the events that an auxiliary activity monitor event counter AMU.AMEVCNTR1<n> counts.
External register AMEVTYPER1<n> bits [31:0] are architecturally mapped to AArch64 System register AMEVTYPER1<n>_EL0[31:0] when FEAT_AMU_EXT32 is implemented.
External register AMEVTYPER1<n> bits [63:0] are architecturally mapped to AArch64 System register AMEVTYPER1<n>_EL0[63:0] when FEAT_AMU_EXT64 is implemented.
External register AMEVTYPER1<n> bits [31:0] are architecturally mapped to AArch32 System register AMEVTYPER1<n>[31:0].
It is IMPLEMENTATION DEFINED whether AMEVTYPER1<n> is implemented in the Core power domain or in the Debug power domain.
This register is present only when FEAT_AMUv1 is implemented. Otherwise, direct accesses to AMEVTYPER1<n> are RES0.
AMEVTYPER1<n> is a:

If <n> is greater than or equal to the number of auxiliary activity monitor event counters, reads of AMEVTYPER1<n> are RAZ. Software must treat reserved accesses as RES0. See 'Access requirements for reserved and unallocated registers'.
AMU.AMCGCR.CG1NC identifies the number of auxiliary activity monitor event counters.
Accesses to this register use the following encodings:
When FEAT_AMU_EXT32 is implementedAccessible at offset 0x480 + (4 * n) from AMU
Accesses on this interface are RO.
Accessible at offset 0x500 + (8 * n) from AMU
Accesses on this interface are RO.
