106 New directory structure. root 5534d 22h /uart16550/trunk/rtl/verilog/uart_debug_if.v
84 The uart_defines.v file is included again in sources. gorban 7950d 11h /uart16550/trunk/rtl/verilog/uart_debug_if.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.
