The TRCIDR13 characteristics are:
Returns the tracing capabilities of the trace unit.
External register TRCIDR13 bits [31:0] are architecturally mapped to AArch64 System register TRCIDR13[31:0].
This register is present only when FEAT_ETE is implemented. Otherwise, direct accesses to TRCIDR13 are RES0.
TRCIDR13 is a 32-bit register.
The TRCIDR13 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 |
NUMCONDSPC |
Indicates the number of special conditional instruction right-hand keys. Conditional instruction tracing is not implemented in ETE and this field is reserved for other trace architectures. Allocated in other trace architectures.
Reserved, RES0.
