EDCIDR2, External Debug Component Identification Register 2
The EDCIDR2 characteristics are:
Provides information to identify an external debug component.
For more information, see 'About the Component Identification scheme'.
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.
This register is required for CoreSight compliance.
EDCIDR2 is a 32-bit register.
The EDCIDR2 bit assignments are:
PRMBL_2, bits [7:0]
Reads as 0x05.
Accessing the EDCIDR2
EDCIDR2 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.
