Bits[11:0] of the address arezero.If DBGDRAR.Valid is zero, the value of this field is UNKNOWN.[31:12] ROMADDR[31:12] Bits[31:12] of the debug component physical address. Bits[11:0] of the address arezero. The ROMADDR[39:32] signal sets the values of the ROMADDR fields.If DBGDRAR.Valid is zero, the value of this field is UNKNOWN.[11:2] - Reserved.[1:0] Valid Valid bits. This field indicates whether the address is valid:b00Address is not valid.b11Address is valid.NoteROMADDRV must be set HIGH if ROMADDR[39:12] is set to a valid value.10.4.10 Breakpoint Extended Value RegistersThe DBGBXVR characteristics are:PurposeHolds a value for use in breakpoint matching, to support VMID matching.Usage constraints Used in conjunction with a DBGBCR and a DBGBVR. See BreakpointControl Registers on page 10-15, and Breakpoint Value Registers onpage 10-14. Each DBGBXVR is associated with a DBGBCR andDBGBVR to form a Breakpoint Register Pair (BRP). DBGBXVRn isassociated with DBGBCRn and DBGBVRn to form breakpoint n.ARM DDI 0438I Copyright © 2011-2013 ARM. All rights reserved. 10-21ID062913Non-Confidential
