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 and FEAT_TRC_EXT is implemented. Otherwise, direct accesses to TRCIDR13 are RES0.
TRCIDR13 is a 32-bit register.
