MK50H25 Overview
(Continued) For added flexibility a transparent mode provides an HDLC transport mechanism without link layer support. This flexible transparent mode may be easily entered and exited without affecting the X.25 link status or the link state variables kept by the MK50H25. In this mode no protocol processing is done and it is up to the user to take care of the upper level software.
