[Figure 1, callout 9]
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.
|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.
