+description: |
+  Xilinx 7 Series FPGAs support a method of loading the bitstream over a
+  parallel port named the slave SelectMAP interface in the documentation. Only
+  the x8 mode is supported where data is loaded at one byte per rising edge of
+  the clock, with the MSB of each byte presented to the D0 pin.
+
+  Datasheets:

I am surprised that AMD/Xilinx still did not update the document to
modern naming (slave->secondary).

+Cc Michal,
Maybe that's something you could push it.

Best regards,
Krzysztof
