Introduction
This document describes the angle clock feature of the enhanced time processor unit and offers practical advise on the application and use of this feature. The note assumes a familiarity with the eTPU and the eTPU_C language used in the byte craft compiler. The eTPU is particularly suited to applications where input and output actions are synchronized to the position of a rotating wheel. The eTPU angle clock provides hardware which, when combined with the proper software, can track the wheel angle through accelerations, decelerations, and a wide range of speeds.
