The DBGAUTHSTATUS_EL1 characteristics are:
Provides information about the state of the IMPLEMENTATION DEFINED authentication interface for debug.
External register DBGAUTHSTATUS_EL1 bits [31:0] are architecturally mapped to AArch64 System register DBGAUTHSTATUS_EL1[31:0] .
External register DBGAUTHSTATUS_EL1 bits [31:0] are architecturally mapped to AArch32 System register DBGAUTHSTATUS[31:0] .
It is IMPLEMENTATION DEFINED whether DBGAUTHSTATUS_EL1 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.
DBGAUTHSTATUS_EL1 is a 32-bit register.
The DBGAUTHSTATUS_EL1 bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |

Reserved, RES0.
Secure non-invasive debug.
ExternalSecureNoninvasiveDebugEnabled() == ExternalSecureInvasiveDebugEnabled().
This field has the same value as DBGAUTHSTATUS_EL1.SID.
Secure non-invasive debug.
SNID | Meaning |
---|---|
0b00 |
Not implemented. EL3 is not implemented and the Effective value of SCR_EL3.NS is 1. |
0b10 |
Implemented and disabled. ExternalSecureNoninvasiveDebugEnabled() == FALSE. |
0b11 |
Implemented and enabled. ExternalSecureNoninvasiveDebugEnabled() == TRUE. |
All other values are reserved.
Secure invasive debug.
SID | Meaning |
---|---|
0b00 |
Not implemented. EL3 is not implemented and the Effective value of SCR_EL3.NS is 1. |
0b10 |
Implemented and disabled. ExternalSecureInvasiveDebugEnabled() == FALSE. |
0b11 |
Implemented and enabled. ExternalSecureInvasiveDebugEnabled() == TRUE. |
All other values are reserved.
Non-secure non-invasive debug.
NSNID | Meaning |
---|---|
0b00 |
Not implemented. EL3 is not implemented and the Effective value of SCR_EL3.NS is 0. |
0b11 |
Implemented and enabled. ExternalNoninvasiveDebugEnabled() == TRUE. |
If the Effective value of SCR_EL3.NS is 1, or if EL3 is implemented and EL2 is not implemented, this field reads as 0b11.
All other values are reserved.
Non-secure non-invasive debug.
NSNID | Meaning |
---|---|
0b00 |
Not implemented. EL3 is not implemented and the Effective value of SCR_EL3.NS is 0. |
0b10 |
Implemented and disabled. ExternalNoninvasiveDebugEnabled() == FALSE. |
0b11 |
Implemented and enabled. ExternalNoninvasiveDebugEnabled() == TRUE. |
All other values are reserved.
Non-secure invasive debug.
NSID | Meaning |
---|---|
0b00 |
Not implemented. EL3 is not implemented and the Effective value of SCR_EL3.NS is 0. |
0b10 |
Implemented and disabled. ExternalInvasiveDebugEnabled() == FALSE. |
0b11 |
Implemented and enabled. ExternalInvasiveDebugEnabled() == TRUE. |
All other values are reserved.
