This is specified in MCC 23.2.2.2 chapter of the QEIWRM. Even if related to the MCC, I suppose this restriction is also applicable to the UMCC.</P><P></P><P><span class="lia-inline-image-display-wrapper" image-alt="ZDSTATE_register.PNG"><img src="https://community.nxp.com/t5/image/serverpage/image-id/8800i303178CEC912F001/image-size/large?v=v2&amp;px=999" role="button" title="ZDSTATE_register.PNG" alt="ZDSTATE_register.PNG" /></span></P><P>We have also tried to configure an 8-bit synchronization pattern which works fine for 8-bit time slots, but data in 16-bit time slots is always shifted, even with a 16-bit pattern.</P><P></P><P>The picture above seems to show a configuration where no pattern is used and data is not shifted (note 3) but the&nbsp;RCVSYNC and ZDSTATE informations are missing...</P><P></P><P>Could someone please provide us with the missing configuration?</P><P></P><P>Many thanks,</P><P>Sébastien</P></BODY></HTML> Mon, 28 Nov 2016 16:27:40 GMT https://community.nxp.com/t5/P-Series/TDM-UMCC-synchronization-in-transparent-mode/m-p/629241#M3725 seblol 2016-11-28T16:27:40Z https://community.nxp.com/t5/P-Series/TDM-UMCC-synchronization-in-transparent-mode/m-p/629242#M3726 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10.0pt; color: black; background: white;">Look at attached file.</SPAN></P><P><SPAN style="font-size: 10.0pt; color: black; background: white;">It is simple program example for the MPC8560 MCC in transparent mode.
