This is the primary Versal ACAP 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 U21. The FT4232HL U20 port assignments are listed in the following table.

Table 1. FT4232HL Port Assignments
FT4232HL U34	Versal ACAP U1
Port AD JTAG	VPK120 JTAG chain
Port BD UART0	PS_UART0 (MIO 42-43)
Port CD UART1	PL_UART1 bank 712
Port DD UART2	U20 system controller UART

The FT4232HL UART interface connections are shown in the following figure.
