AMPIDR3, Activity Monitors Peripheral Identification Register 3

The AMPIDR3 characteristics are:

Purpose

Provides information to identify an activity monitors component.

For more information, see 'About the Peripheral identification scheme'.

Configuration

It is IMPLEMENTATION DEFINED whether AMPIDR3 is implemented in the Core power domain or in the Debug power domain.

This register is present only when FEAT_AMUv1 is implemented and an implementation implements AMPIDR3. Otherwise, direct accesses to AMPIDR3 are RES0.

Attributes

AMPIDR3 is a 32-bit register.

This register is part of the AMU block.
