Notes:
1. The output swing and pre-emphasis levels are programmable using the attributes discussed in the
Zynq UltraScale+ MPSoC Technical Reference Manual (UG1085), and can result in values lower than reported in this table.
2. Other values can be used as appropriate to conform to specific protocols and standards.
