// Revision 1.38 2002/07/22 23:02:23 gorban
|
|
// 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.
