106 New directory structure. root 5572d 02h /uart16550/tags/rel_3/
102 This commit was manufactured by cvs2svn to create tag 'rel_3'. 7326d 00h /tags/rel_3/
101 Added 2 LSB address generation dependent on select lines and LITLE/BIG endian when UART is in 32-bit mode. tadejm 7326d 00h /trunk/
100 Repaired bug in receiver. When stop bit is sampled and next clock RX input was '0', state machine stayed locked until next '1' which cause loosing at least start bit in case of larger difference of bit times between 2 UARTs. tadejm 7326d 01h /trunk/
99 Added synchronizer flops for RX input. tadejm 7326d 01h /trunk/
98 Added to synchronize RX input to Wishbone clock. tadejm 7326d 01h /trunk/
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 7381d 08h /trunk/
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 7381d 08h /trunk/
94 Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead when only TX FIFO gets empty. This causes testcases not to finish. tadejm 7381d 08h /trunk/
93 Testbench with complete selfchecking. BUG is that THRE status is set at the end of last sent bit when TX FIFO is empty instead when only TX FIFO gets empty. This causes testcases not to finish. tadejm 7381d 08h /trunk/
92 This is revision 1.4, revision 1.5 was put there by mistake. simons 7495d 01h /trunk/
91 Removed files due to new complete testbench. tadejm 7495d 17h /trunk/
90 Add Flextronics header avisha 7497d 23h /trunk/
89 adjusted comment + define dries 7578d 05h /trunk/
88 added clearing the receiver fifo statuses on resets gorban 7640d 18h /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 7670d 20h /trunk/
86 restored include for uart_defines.v in uart_test.v gorban 7941d 00h /trunk/
85 Updated documentation to include latest changes. gorban 7974d 16h /trunk/
84 The uart_defines.v file is included again in sources. gorban 7987d 15h /trunk/
83 Reverted to include uart_defines.v file in other files again. gorban 7987d 15h /trunk/
82 Updated to work with latest core. gorban 7994d 13h /trunk/
81 Added lastest additions. gorban 7994d 13h /trunk/
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 7994d 13h /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 7994d 13h /trunk/
75 Endian define added. Big Byte Endian is selected by default. mohor 8147d 19h /trunk/
74 tf_overrun signal was disabled since it was not used gorban 8152d 21h /trunk/
73 major bug in 32-bit mode that prevented register access fixed. gorban 8159d 20h /trunk/
72 UART PHY added. Files are fully operational, working on HW. mohor 8173d 03h /trunk/
71 Removed confusing comment gorban 8184d 16h /trunk/
70 tf_pop was too wide. Now it is only 1 clk cycle width. mohor 8190d 01h /trunk/
