The DBGAUTHSTATUS_EL1 characteristics are:
Provides information about the state of the IMPLEMENTATION DEFINED authentication interface for debug.
AArch64 System register DBGAUTHSTATUS_EL1 bits [31:0] are architecturally mapped to AArch32 System register DBGAUTHSTATUS[31:0] .
AArch64 System register DBGAUTHSTATUS_EL1 bits [31:0] are architecturally mapped to External register DBGAUTHSTATUS_EL1[31:0] .
DBGAUTHSTATUS_EL1 is a 64-bit register.
The DBGAUTHSTATUS_EL1 bit assignments are:
