The detailed Zynq UltraScale+ RFSoC connecons for the feature described in this secon are
documented in the ZCU670 board XDC le, referenced in Appendix B: Xilinx Design Constraints.
UART0 (MIO 18-19)
[Figure 2, callout 8]
This is the primary Zynq UltraScale+ RFSoC PS-side UART interface and is connected to the FTDI
U29 FT4232HL USB-to-Quad-UART Bridge port B through TXS0108E level-shier U32.
The FT4232HL U29 port assignments are listed in the following table.
