98 Added to synchronize RX input to Wishbone clock. tadejm 7329d 08h /
97 This commit was manufactured by cvs2svn to create tag 'rel_2'. 7384d 16h /
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 7384d 16h /

92 This is revision 1.4, revision 1.5 was put there by mistake. simons 7498d 09h /
91 Removed files due to new complete testbench. tadejm 7499d 00h /
90 Add Flextronics header avisha 7501d 07h /
89 adjusted comment + define dries 7581d 12h /
88 added clearing the receiver fifo statuses on resets gorban 7644d 01h /
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 7674d 03h /
86 restored include for uart_defines.v in uart_test.v gorban 7944d 07h /
85 Updated documentation to include latest changes. gorban 7977d 23h /
84 The uart_defines.v file is included again in sources. gorban 7990d 23h /
83 Reverted to include uart_defines.v file in other files again. gorban 7990d 23h /
82 Updated to work with latest core. gorban 7997d 20h /
81 Added lastest additions. gorban 7997d 21h /
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 7997d 21h /
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.
