TRCPRGCTLR, Trace Programming Control Register

The TRCPRGCTLR characteristics are:

Purpose

Enables the trace unit.

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

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

TRCPRGCTLR is a 32-bit register.

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.
