Ethernet TAP probe specifications
The following figure shows the dimensions of the Ethernet TAP probe.
Electrical characteristics
The Ethernet TAP probe affects the load on only those signals that are connected to the debug port connector. Loading depends on the method used to connect the Ethernet TAP probe to the target system. See Connecting to target system topic for a description of each connection method.
The Ethernet TAP probe affects the target processor and target electrical characteristics as little as possible. Care, however, should be taken in designing the target to accommodate the small signal delays associated with any in-circuit emulator or other test equipment.
The Ethernet TAP probe automatically supports target signal levels from 1.8V to 3.3V.
Physical characteristics
The Ethernet TAP probe was carefully designed to be as small as possible. Even so, it may not physically fit in all target systems.
If you are unable to connect to the debug port on your target system, or if your target system does not have a debug port connector, see Connecting probe tip to debug port header using extension cable topic.
