3.13.12. TPIU EXCTL In Port register

The EXTCTL_In_Port register characteristics are:

Purpose

Two ports can be used as a control and feedback mechanism for any serializers, pin sharing multiplexers, or other solutions that might be added to the trace output pins either for pin control or a high speed trace port solution. These ports are raw register banks that sample or export the corresponding external pins. The output register bank is set to all 0s on reset. The input registers sample the incoming signals and are therefore undefined.

Usage constraints

There are no usage constraints.

Configurations

This register is available in all configurations.
