PMDEVTYPE, Performance Monitors Device Type register

The PMDEVTYPE characteristics are:


Indicates to a debugger that this component is part of a PEs performance monitor interface.


Implementation of this register is OPTIONAL.

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.


PMDEVTYPE is a 32-bit register.

Field descriptions

The PMDEVTYPE bit assignments are:


Bits [31:8]

Reserved, RES0.

SUB, bits [7:4]

Subtype. Must read as 0x1 to indicate this is a component within a PE.

MAJOR, bits [3:0]

Major type. Must read as 0x6 to indicate this is a performance monitor component.

Accessing the PMDEVTYPE

PMDEVTYPE can be accessed through the external debug interface:


This interface is accessible as follows:

  • When FEAT_DoPD is not implemented or IsCorePowered() accesses to this register are RO.
  • Otherwise accesses to this register generate an error response.
