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.
The PMDEVTYPE bit assignments are:
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.
