106 New directory structure. root 5548d 12h /uart16550/trunk/rtl/verilog/uart_rfifo.v
88 added clearing the receiver fifo statuses on resets gorban 7617d 04h /uart16550/trunk/rtl/verilog/uart_rfifo.v
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 06h /uart16550/trunk/rtl/verilog/uart_rfifo.v
84 The uart_defines.v file is included again in sources. gorban 7964d 01h /uart16550/trunk/rtl/verilog/uart_rfifo.v
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.
