PMCIDR2, Performance Monitors Component Identification Register 2

The PMCIDR2 characteristics are:

Purpose

Provides information to identify a Performance Monitor component.

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

Configuration

This register is present only when FEAT_PMUv3_EXT is implemented and an implementation implements PMCIDR2. Otherwise, direct accesses to PMCIDR2 are RES0.

If FEAT_DoPD is implemented, this register is in the Core power domain. If FEAT_DoPD is not implemented, this register is in the Debug power domain.

This register is required for CoreSight compliance.

Attributes

PMCIDR2 is a 32-bit register.

This register is part of the PMU block.
