TRCIMSPEC<n>, Trace IMP DEF Register <n>, n = 1 - 7

The TRCIMSPEC<n> characteristics are:

Purpose

These registers might return information that is specific to an implementation, or enable features specific to an implementation to be programmed. The product Technical Reference Manual describes these registers.

Configuration

External register TRCIMSPEC<n> bits [31:0] are architecturally mapped to AArch64 System register TRCIMSPEC<n>[31:0].

This register is present only when an implementation implements TRCIMSPEC<n>, FEAT_ETE is implemented and FEAT_TRC_EXT is implemented. Otherwise, direct accesses to TRCIMSPEC<n> are RES0.

Attributes

TRCIMSPEC<n> is a 32-bit register.

IMPLEMENTATION DEFINED

IMPLEMENTATION DEFINED, bits [31:0]

IMPLEMENTATION DEFINED.

This field reads as an IMPLEMENTATION DEFINED value and writes to this field have IMPLEMENTATION DEFINED behavior.

Accessing TRCIMSPEC<n>

TRCIMSPEC<n> can be accessed through the external debug interface:

Component	Offset	Instance
ETE	0x1C0 + (4 * n)	TRCIMSPEC<n>

This interface is accessible as follows:

When OSLockStatus(), or !AllowExternalTraceAccess() or !IsTraceCorePowered(), accesses to this register generate an error response.
Otherwise, accesses to this register are RW.
