13.7.34 Trace Integration Mode Control register

The TRCITCTRL characteristics are:
Purpose
Controls whether the trace unit is in integration mode.
Usage constraints
  • Accessible only from the memory-mapped interface or from an external agent such as a debugger.
  • If the IME bit changes from one to zero then ARM recommends that the trace unit is reset. Otherwise the trace unit might generate incorrect or corrupt trace and the trace unit resources might behave unexpectedly.
Configurations
Available in all configurations.
Attributes
A 32-bit RW management register. The register is reset to zero.

Integration mode enable bit. The possible values are:
0The trace unit is not in integration mode.
1
The trace unit is in integration mode. This mode enables:
  • A debug agent to perform topology detection.
  • SoC test software to perform integration testing.
The TRCITCTRL can be accessed through the internal memory-mapped interface and the external debug interface, offset 0xF00.
