AMEVTYPER1<n>, Activity Monitors Event Type Registers 1, n = 0 - 15

The AMEVTYPER1<n> characteristics are:

Purpose

Provides information on the events that an auxiliary activity monitor event counter AMEVCNTR1<n> counts.

Configuration

External register AMEVTYPER1<n> bits [31:0] are architecturally mapped to AArch64 System register AMEVTYPER1<n>_EL0[31:0] .

External register AMEVTYPER1<n> bits [31:0] are architecturally mapped to AArch32 System register AMEVTYPER1<n>[31:0] .

The power domain of AMEVTYPER1<n> is IMPLEMENTATION DEFINED.

This register is present only when AMUv1 is implemented. Otherwise, direct accesses to AMEVTYPER1<n> are RES0.

Attributes

AMEVTYPER1<n> is a 32-bit register.

Field descriptions

The AMEVTYPER1<n> bit assignments are:

Bits [31:25]

Reserved, RAZ.

Bits [24:16]

Reserved, RES0.

evtCount, bits [15:0]

Event to count. The event number of the event that is counted by the auxiliary activity monitor event counter AMEVCNTR1<n>.

It is IMPLEMENTATION DEFINED what values are supported by each counter.

If software writes a value to this field which is not supported by the corresponding counter AMEVCNTR1<n>, then:

• It is UNPREDICTABLE which event will be counted.
• The value read back is UNKNOWN.

If the corresponding counter AMEVCNTR1<n> is enabled, writes to this register have UNPREDICTABLE results.

Accessing the AMEVTYPER1<n>

If <n> is greater than or equal to the number of auxiliary activity monitor event counters, reads of AMEVTYPER1<n> are RAZ/WI. Software must treat reserved accesses as RES0. See 'Access requirements for reserved and unallocated registers'.

AMEVTYPER1<n> can be accessed through the memory-mapped interfaces:

Accesses on this interface are RO.
