-The UART_D16950  library simplifies usage of the UART module of FT90x family.

-Some of module features:
  1)  Software compatible with 450, 550, 750 and 950 UARTs
  2)  Separate configurable BAUD clock line
  3)  Configuration capability
  4)  Two modes of operation: UART mode and FIFO mode
  5)  Majority voting logic
  6)  16 / 128 bytes FIFO for TX and RX in FIFO mode to reduce the interrupt frequency
  7)  Adds or deletes standard asynchronous communication bits to or from the serial data
  8)  Double buffering for both TX and RX in UART mode
  9)  Independently controlled transmit, receive, line status and data set interrupts
  10) Programmable baud generator
  11) Modem control functions (CTS, RTS, DSR, DTR, RI and DCD)
  12) Programmable automatic out-of-band Flow Control logic through Auto-RTS and Auto-CTS
  13) Programmable automatic Flow Control logic using DTR and DSR
  14) Programmable automatic in-band Flow Control logic using XON / XOFF characters
  15) Programmable special characters detection
  16) Trigger levels for TX and RX FIFO interrupts, automatic in-band and out-of-band flow control
  17) RS-485 buffer enable signals
  18) TX and RX disable capability
  19) Fully programmable serial interface characteristics
