106 New directory structure. root 5548d 10h /uart16550/tags/rel_2/
97 This commit was manufactured by cvs2svn to create tag 'rel_2'. 7357d 16h /tags/rel_2/
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 7357d 16h /trunk/

92 This is revision 1.4, revision 1.5 was put there by mistake. simons 7471d 09h /trunk/
91 Removed files due to new complete testbench. tadejm 7472d 00h /trunk/
90 Add Flextronics header avisha 7474d 07h /trunk/
89 adjusted comment + define dries 7554d 12h /trunk/
88 added clearing the receiver fifo statuses on resets gorban 7617d 01h /trunk/
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 7647d 03h /trunk/
86 restored include for uart_defines.v in uart_test.v gorban 7917d 07h /trunk/
85 Updated documentation to include latest changes. gorban 7950d 23h /trunk/
84 The uart_defines.v file is included again in sources. gorban 7963d 23h /trunk/
83 Reverted to include uart_defines.v file in other files again. gorban 7963d 23h /trunk/
82 Updated to work with latest core. gorban 7970d 20h /trunk/
81 Added lastest additions. gorban 7970d 21h /trunk/
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 7970d 21h /trunk/
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.		 gorban 7970d 21h /trunk/
75 Endian define added. Big Byte Endian is selected by default. mohor 8124d 03h /trunk/
74 tf_overrun signal was disabled since it was not used gorban 8129d 04h /trunk/
73 major bug in 32-bit mode that prevented register access fixed. gorban 8136d 03h /trunk/
72 UART PHY added. Files are fully operational, working on HW. mohor 8149d 11h /trunk/
71 Removed confusing comment gorban 8161d 00h /trunk/
70 tf_pop was too wide. Now it is only 1 clk cycle width. mohor 8166d 08h /trunk/
69 More than one character was stored in case of break. End of the break
was not detected correctly.		 mohor 8174d 23h /trunk/
68 lsr[7] was not showing overrun errors. mohor 8178d 06h /trunk/
67 Missing declaration of rf_push_q fixed. mohor 8185d 06h /trunk/
66 rx push changed to be only one cycle wide. mohor 8185d 06h /trunk/
