Table 5. Lane Mapping Tab
Parameter Choices Notes
Phy Lane n clk, data0, data1, data2, data3, unused The MIPI TX block supports 4 data lanes and 1 clock lane. For each lane, specify whether to use it as clock or data. The lane mapping must be unique, which the software enforces.
Swap P&N Pin On or off Turn on to change which pin is P or N. This setting can be helpful when laying out your board.
