The Coresight TMC Control Unit(CTCU) device hosts miscellaneous configuration registers to control various features related to TMC ETR device.

The CTCU device works as a helper device physically connected to the TMC ETR device.

ETR0ATID0-ETR0ATID3 CTCU ETR1ATID0-ETR1ATID3

Each ETR has four ATID registers with 128 bits long in total. e.g. ETR0ATID0-ETR0ATID3 registers are used by ETR0 device.
