AMCIDR1, Activity Monitors Component Identification Register 1

The AMCIDR1 characteristics are:

Purpose

Provides information to identify an activity monitors component.

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

Configuration

It is IMPLEMENTATION DEFINED whether AMCIDR1 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 AMCIDR1. Otherwise, direct accesses to AMCIDR1 are RES0.

Attributes

AMCIDR1 is a 32-bit register.

This register is part of the AMU block.
