95 Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead only when TX FIFO is empty. This causes testcases not to finish. tadejm 7506d 23h /

92 This is revision 1.4, revision 1.5 was put there by mistake. simons 7620d 16h /
91 Removed files due to new complete testbench. tadejm 7621d 07h /
90 Add Flextronics header avisha 7623d 14h /
89 adjusted comment + define dries 7703d 20h /
88 added clearing the receiver fifo statuses on resets gorban 7766d 09h /
87 This fixes errors in some cases when data is being read and put to the FIFO at the same time. Patch is submitted by Scott Furman. Update is very recommended. gorban 7796d 10h /
86 restored include for uart_defines.v in uart_test.v gorban 8066d 14h /
85 Updated documentation to include latest changes. gorban 8100d 06h /
84 The uart_defines.v file is included again in sources. gorban 8113d 06h /
83 Reverted to include uart_defines.v file in other files again. gorban 8113d 06h /
82 Updated to work with latest core. gorban 8120d 04h /
81 Added lastest additions. gorban 8120d 04h /
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 8120d 04h /
79 Bug Fixes:
* Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
Problem reported by Kenny.Tung.
* Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.

Improvements:
* Made FIFO's as general inferrable memory where possible.
So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
This saves about 1/3 of the Slice count and reduces P&R and synthesis times.

* Added optional baudrate output (baud_o).
This is identical to BAUDOUT* signal on 16550 chip.
It outputs 16xbit_clock_rate - the divided clock.
It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
