3.4 UART Interface
When the data and control buses are configured in UART mode, the interface implements a standard
asynchronous serial UART port with flow control. The UART can support baud rates from 300 baud to
3Mbaud. The UART interface is described more fully in the VNC2 datasheet please refer to:-
3.4.1 Signal Description – UART Interface
The UART signals can be programmed to a choice of available I/O pins. Table 3.3 explains the available
pins for each of the UART signals.
