USB-UART Connection
...
Because of limited MIO pins available the USB-UART is shared with the bus connector UART. A 2-channel single-pole double throw (SPDT) bidirectional switch is used to switch between the two connectors. By default it's routed to the USB-UART but by setting pin PS_MIO_51 high the data is routed to pin 3 and 4 on the bus connector.

| PS_MIO_14 | TX | ||
| PS_MIO_15 | RX | ||
| PS_MIO_51 | SPDT Switch | Set to '0' for USB and '1' for bus connector |
