4.1 UART Interface
When the Vinco data and control buses are configured as a UART interface, the interface implements a
standard asynchronous serial UART port with flow control. The UART can support baud rates from
300baud to 6Mbaud. The UART interface is described in more detail in the Vinculum-II datasheet please
refer to: -
4.1.1 Signal Description – UART Interface
The UART signals can be programmed to a choice of available I/O pins. Table 4.1 explains the available
pins for each of the UART signals. This is a subset of what the VNC2-64Q is capable of to avoid conflict
with other functions on the Vinco module.
