3.5 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 300baud to
3Mbaud. The UART interface is described more fully in a Vinculum-II datasheet please refer to:-
website.
3.5.1 Signal Description – UART Interface
The UART signals can be programmed to a choice of I/O pin available. Table 3.4 explains the available
pins for each of the UART signals.

designs. uart_tx_active may be used
to signal that a transmit operation is
in progress.The uart_tx_active signal
will be set high one bit-time before
data is transmitted and return low
one bit time after the last bit of a
data frame has been transmitted
