PMC MIO[42:43] UART0
[Figure 1, callout 9]
This is the primary Versal device PS-side UART interface. MIO42 (RX_IN) and MIO43
(TX_OUT) are connected to FTDI FT4232HL U20 USB-to-Quad-UART bridge port BD
through TI SN74AVC4T245 level-shifters U18 and U271. The FT4232HL U20 port
assignments are listed in the following table.
