The DBGDEVID1 characteristics are:
- Adds to the information given by the DBGDIDR by
describing other features of the debug implementation.
- Usage constraints
The accessibility to the DBGDEVID1 by Exception
||EL3(SCR.NS = 1)
||EL3(SCR.NS = 0)
The DBGDEVID1 is Common to Secure and Non-secure

Indicates the offset applied to PC samples
returned by reads of EDPCSR. The value is:
|EDPCSR samples have no offset applied and do not
sample the instruction set state in the AArch32 state.
To access the DBGDEVID1 in AArch32 state, read the CP14 register
