The TRCDEVID characteristics are:

Purpose

Provides discovery information for the component.

For additional information, see the CoreSight Architecture Specification.

External register TRCDEVID bits [31:0] are architecturally mapped to AArch64 System register TRCDEVID[31:0].

This register is present only when FEAT_ETE is implemented and FEAT_TRC_EXT is implemented. Otherwise, direct accesses to TRCDEVID are RES0.

TRCDEVID is a 32-bit register.
