TRCITCTRL, Integration Mode Control Register

The TRCITCTRL characteristics are:

Purpose

A component can use TRCITCTRL to dynamically switch between functional mode and integration mode. In integration mode, topology detection is enabled. After switching to integration mode and performing integration tests or topology detection, reset the system to ensure correct behavior of CoreSight and other connected system components.

For additional information, see the CoreSight Architecture Specification.

Configuration

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

Attributes

TRCITCTRL is a 32-bit register.
