TRCIDR11, ID Register 11
The TRCIDR11 characteristics are:
Purpose
Returns the tracing capabilities of the trace unit.
Configuration
External register TRCIDR11 bits [31:0] are architecturally mapped to AArch64 System register TRCIDR11[31:0] .
This register is present only when ETE is implemented. Otherwise, direct accesses to TRCIDR11 are RES0.
Attributes
TRCIDR11 is a 32-bit register.
Field descriptions
The TRCIDR11 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 |
| NUMP1SPC | |||||||||||||||||||||||||||||||
NUMP1SPC, bits [31:0]
When TRCIDR0.TRCDATA != 0b00:
When TRCIDR0.TRCDATA != 0b00:
Indicates the number of special P1 right-hand keys. Data tracing is not implemented in ETE and this field is reserved for other trace architectures. Allocated in other trace architectures.
Otherwise:
Otherwise:
Reserved, RES0.
Accessing the TRCIDR11
TRCIDR11 can be accessed through the external debug interface:
| Component | Offset |
|---|---|
| ETE | 0x18C |
This interface is accessible as follows:
- When OSLockStatus() or !IsTraceCorePowered() access to this register returns an Error.
- Otherwise access to this register is RO.
