TRBDEVID1: Device Configuration Register 1

Purpose

Provides discovery information for the component.

For additional information, see the CoreSight Architecture Specification.

TRBDEVID1 is in the Core power domain.

This register is present only when FEAT_TRBE_EXT is implemented. Otherwise, direct accesses to TRBDEVID1 are RES0.

TRBDEVID1 is a 32-bit register.

RES0								PMG_MAX								PARTID_MAX

Reserved, RES0.

Largest permitted PMG value. The TRBMPAM_EL1.PMG field must implement at least enough bits to represent TRBDEVID1.PMG_MAX.

This field has an IMPLEMENTATION DEFINED value.

Access to this field is RO.

Reserved, RES0.

Largest permitted PARTID value. The TRBMPAM_EL1.PARTID field must implement at least enough bits to represent TRBDEVID1.PARTID_MAX.

This field has an IMPLEMENTATION DEFINED value.

Access to this field is RO.

Reserved, RES0.

This interface is accessible as follows:

When DoubleLockStatus() or !IsCorePowered(), accesses to this register generate an error response.
Otherwise, accesses to this register are RO.
