15.5.3 CoreSight device component register IDs

The documentation for a CoreSight component lists its component registers and their address offsets. For example, the CoreSight STM component has a Trace Control and Status Register called STMTCSR which has an offset of 0xE80. To access this register through the IDevice interface, you need to know its register ID. To determine the ID, divide the documented offset by four. For example, the register ID for the STMTCSR register is 0x3A0, which is 0xE80/4.
