92 This is revision 1.4, revision 1.5 was put there by mistake. simons 7494d 20h /
91 Removed files due to new complete testbench. tadejm 7495d 11h /
90 Add Flextronics header avisha 7497d 18h /
89 adjusted comment + define dries 7578d 00h /
88 added clearing the receiver fifo statuses on resets gorban 7640d 13h /
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 15h /
86 restored include for uart_defines.v in uart_test.v gorban 7940d 19h /
85 Updated documentation to include latest changes. gorban 7974d 10h /
84 The uart_defines.v file is included again in sources. gorban 7987d 10h /
83 Reverted to include uart_defines.v file in other files again. gorban 7987d 10h /
82 Updated to work with latest core. gorban 7994d 08h /
81 Added lastest additions. gorban 7994d 08h /
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 7994d 08h /
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.
