SelectMAP Bit Order - SelectMAP Bit Order - UG860

The SelectMAP interface is typically driven by a user application residing on a microprocessor, microcontroller, or another FPGA or SoC. The Spartan UltraScale+ FPGA automatically detects the bus width during configuration. For these applications, it is valuable to understand how the data ordering in the programmable Spartan UltraScale+ device's image corresponds to the data ordering expected by the device's interface when debugging. The following table shows how to load the SelectMAP PDI data bits onto the SelectMAP data pins.
