EDDEVID2, External Debug Device ID register 2

The EDDEVID2 characteristics are:

Purpose

Reserved for future descriptions of features of the debug implementation.

Configuration

It is IMPLEMENTATION DEFINED whether EDDEVID2 is implemented in the Core power domain or in the Debug power domain.

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.

Attributes

EDDEVID2 is a 32-bit register.

Field descriptions

The EDDEVID2 bit assignments are:

313029282726252423222120191817161514131211109876543210
RES0

Bits [31:0]

Reserved, RES0.

Accessing the EDDEVID2

EDDEVID2 can be accessed through the external debug interface:

ComponentOffsetInstance
Debug0xFC0EDDEVID2

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.
