AMDEVTYPE, Activity Monitors Device Type Register

The AMDEVTYPE characteristics are:

Purpose

Indicates to a debugger that this component is part of a PE's performance monitor interface.

Configuration

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

Attributes

AMDEVTYPE is a 32-bit register.

This register is part of the AMU block.
