The EDWAR characteristics are:
Returns the virtual data address being accessed when a Watchpoint Debug Event was triggered.
EDWAR is in the Core power domain.
EDWAR is in the Core power domain.
RW fields in this register reset to architecturally UNKNOWN values. These apply only on a Cold reset. The register is not affected by a Warm reset and is not affected by an External debug reset.
EDWAR is a 64-bit register.
The EDWAR bit assignments are:
63 | 62 | 61 | 60 | 59 | 58 | 57 | 56 | 55 | 54 | 53 | 52 | 51 | 50 | 49 | 48 | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 | 39 | 38 | 37 | 36 | 35 | 34 | 33 | 32 |

Watchpoint address. The data virtual address being accessed when a Watchpoint Debug Event was triggered and caused entry to Debug state. This address must be within a naturally-aligned block of memory of power-of-two size no larger than the DC ZVA block size.
The value of this register is UNKNOWN if the PE is in Non-debug state, or if Debug state was entered other than for a Watchpoint debug event.
The value of EDWAR[63:32] is UNKNOWN if Debug state was entered for a Watchpoint debug event taken from AArch32 state.
The EDWAR is subject to the same alignment rules as the reporting of a watchpointed address in the FAR. See 'Determining the memory location that caused a Watchpoint exception' in the Arm® Architecture Reference Manual, Armv8, for Armv8-A architecture profile, section D2 (AArch64 Self-hosted Debug)
On a Cold reset, this field resets to an architecturally UNKNOWN value.
