The TRCIDR10 characteristics are:
Returns the tracing capabilities of the trace unit.
External register TRCIDR10 bits [31:0] are architecturally mapped to AArch64 System register TRCIDR10[31:0].
This register is present only when FEAT_ETE is implemented and FEAT_TRC_EXT is implemented. Otherwise, direct accesses to TRCIDR10 are RES0.
TRCIDR10 is a 32-bit register.
