I just received additional information from the design team, it seems this feature was added to resolve a bug that was available in previous iterations of the eQEP peripheral all the way up until TMS320F28004x family (eQEP type 1). It seems on QEPI direction change, the incoming posedge of QA could erroneously update/reset the position counter of the eQEP. From our discussion, this bit only needs to be enabled if the application requires a direction change occurring at the same time as an incoming QEPI signal, or when they may see erroneous PC resets. We will work on adding more information about this to our documentation
