The EDCIDR0 characteristics are:
Provides information to identify an external debug component.
For more information see 'About the Component identification scheme' in the Arm® Architecture Reference Manual, Armv8, for Armv8-A architecture profile, section H8 (About the External Debug Registers).
It is IMPLEMENTATION DEFINED whether EDCIDR0 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.
This register is required for CoreSight compliance.
EDCIDR0 is a 32-bit register.
The EDCIDR0 bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
