1-0 | FCHAR | R/W | 00 | Specify which comma character is used to denote end-of-frame. This character is transmitted opportunistically (see the Frame and Multiframe Monitoring section).
0: Use K28.7 (default, JESD204B compliant) 1: Use K28.1 (not JESD204B compliant) 2: Use K28.5 (not JESD204B compliant) 3: Reserved When using a JESD204B receiver, always use FCHAR = 0. When using a general-purpose 8b, 10b receiver, the K28.7 character may cause issues. When K28.7 is combined with certain data characters, a false, misaligned comma character can result, and some receivers realign to the false comma. To avoid this condition, program FCHAR to 1 or 2. Only change this register when JESD_EN is 0. |
