EDDEVTYPE, External Debug Device Type register
The EDDEVTYPE characteristics are:
Indicates to a debugger that this component is part of a PEs debug logic.
It is IMPLEMENTATION DEFINED whether EDDEVTYPE is implemented in the Core power domain or in the Debug power domain.
Implementation of this register is OPTIONAL.
If ARMv8.3-DoPD is implemented, this register is in the Core power domain. If ARMv8.3-DoPD is not implemented, this register is in the Debug power domain.
EDDEVTYPE is a 32-bit register.
The EDDEVTYPE 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 0x5 to indicate this is a debug logic component.
Accessing the EDDEVTYPE
EDDEVTYPE can be accessed through the external debug interface:
This interface is accessible as follows:
- When ARMv8.3-DoPD is not implemented or IsCorePowered() accesses to this register are RO.
- Otherwise accesses to this register generate an error response.
