Integration mode enable bit. The possible values are:

0The trace unit is not in integration mode.

The trace unit is in integration mode. This mode enables:

  • A debug agent to perform topology detection.
  • SoC test software to perform integration testing.

Bit fields and details not provided in this description are architecturally defined. See the Arm® Architecture Reference Manual Armv8, for Armv8-A architecture profile.

The TRCITCTRL can be accessed through the external debug interface, offset 0xF00.
