The DLPC6540 Controller DMD interface supports two High Speed Serial Interface (HSSI) output-only interfaces for data transmission, a single low speed LVDS output-only interface for command write transactions, as well as a low speed single-ended input interface used for command read transactions. Each HSSI port supports full data-only inter-lane remapping within the port, but not between ports. When utilizing this feature, each unique data lane pair can only be mapped to one unique destination data lane pair, and Intra-lane remapping (i.e. swapping P with N) is not supported. In addition, the two HSSI ports can also be swapped. Lane and port remapping (specified in flash) can help with board layout as needed. The number of HSSI ports and number of HSSI lanes/per HSSI port required are based on DMD type and DMD display resolution. Table 7-15 shows some remapping examples. When both ports are used, they do not need to have the same pin mapping.
