PMDEVTYPE, Performance Monitors Device Type register

The PMDEVTYPE characteristics are:

Purpose

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

Configuration

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

Attributes

PMDEVTYPE is a 32-bit register.

This register is part of the PMU block.

Accessing PMDEVTYPE

Accesses to this register use the following encodings:

Accessible at offset 0xFCC from PMU

When FEAT_DoPD is implemented and !IsCorePowered(), accesses to this register generate an error response.
Otherwise, accesses to this register are RO.
