98 Added to synchronize RX input to Wishbone clock. tadejm 7317d 22h /
97 This commit was manufactured by cvs2svn to create tag 'rel_2'. 7373d 05h /
96 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 sauses testcases not to finish. tadejm 7373d 05h /

92 This is revision 1.4, revision 1.5 was put there by mistake. simons 7486d 22h /
91 Removed files due to new complete testbench. tadejm 7487d 14h /
90 Add Flextronics header avisha 7489d 20h /
89 adjusted comment + define dries 7570d 02h /
88 added clearing the receiver fifo statuses on resets gorban 7632d 15h /
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 7662d 17h /
86 restored include for uart_defines.v in uart_test.v gorban 7932d 21h /
85 Updated documentation to include latest changes. gorban 7966d 13h /
84 The uart_defines.v file is included again in sources. gorban 7979d 12h /
83 Reverted to include uart_defines.v file in other files again. gorban 7979d 12h /
82 Updated to work with latest core. gorban 7986d 10h /
81 Added lastest additions. gorban 7986d 10h /
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 7986d 10h /
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.
