2.1. TAP interface

The ETM7 is programmed using a TAP interface. The structure of the TAP interface is shown in Figure 2.1 .

Figure 2.1. ETM7 TAP structure

The ETM7 TAP is logically part of the ARM that it is connected to. That is, Multi-ICE only detects one TAP in a single ARM7 ETM system.

The ETM7 uses scan chain 6. For details, refer to the Embedded Trace Macrocell Specification.
