CTIAUTHSTATUS, CTI Authentication Status register
The CTIAUTHSTATUS characteristics are:
Purpose
Provides information about the state of the IMPLEMENTATION DEFINED authentication interface for CTI.
Configuration
CTIAUTHSTATUS is in the Debug power domain.
This register is OPTIONAL, and is required for CoreSight compliance.
Attributes
CTIAUTHSTATUS is a 32-bit register.
Field descriptions
The CTIAUTHSTATUS bit assignments are:
Bits [31:8]
Reserved, RES0.
Bits [7:4]
Reserved, RAZ.
NSNID, bits [3:2]
If EL3 is implemented, this field holds the same value as DBGAUTHSTATUS_EL1.NSNID.
If EL3 is not implemented and the implemented Security state is Secure state, this field holds the same value as DBGAUTHSTATUS_EL1.SNID.
NSID, bits [1:0]
If EL3 is implemented, this field holds the same value as DBGAUTHSTATUS_EL1.NSID.
If EL3 is not implemented and the implemented Security state is Secure state, this field holds the same value as DBGAUTHSTATUS_EL1.SID.
Accessing the CTIAUTHSTATUS
CTIAUTHSTATUS can be accessed through the external debug interface:
Component | Offset | Instance |
---|---|---|
CTI | 0xFB8 | CTIAUTHSTATUS |
Accesses on this interface are RO.
