parallel trace interface (MIPI) (PTI)

Parallel Trace Interface(PTI) is a parallel MIPI interface specified by the MIPIAlliance.

The PTI interface consists of several data signals and a clock that can be used to export data about system functionality and behavior to a host system for analysis and display. The data exported through the MIPI-PTI interface allows developers to track, or trace, some of the system activity. For this reason, such interfaces are commonly referred to as trace interfaces or trace ports.
