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 300baud to
3Mbaud. The UART interface is described more fully in a Vinculum-II datasheet please refer to:-

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
