Rev	Log message	Author	Age	Path
106	New directory structure.	root	5562d 18h	/uart16550/trunk/rtl/verilog/uart_receiver.v
103	Brandl Tobias repaired a bug regarding frame error in receiver when brake is received.	tadejm	7288d 14h	/uart16550/trunk/rtl/verilog/uart_receiver.v
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	7316d 17h	/uart16550/trunk/rtl/verilog/uart_receiver.v
84	The uart_defines.v file is included again in sources.	gorban	7978d 07h	/uart16550/trunk/rtl/verilog/uart_receiver.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.	gorban	7985d 05h	/uart16550/trunk/rtl/verilog/uart_receiver.v
69	More than one character was stored in case of break. End of the break was not detected correctly.	mohor	8189d 08h	/uart16550/trunk/rtl/verilog/uart_receiver.v
67	Missing declaration of rf_push_q fixed.	mohor	8199d 15h	/uart16550/trunk/rtl/verilog/uart_receiver.v
66	rx push changed to be only one cycle wide.	mohor	8199d 15h	/uart16550/trunk/rtl/verilog/uart_receiver.v
64	Warnings cleared.	mohor	8200d 20h	/uart16550/trunk/rtl/verilog/uart_receiver.v
63	Synplicity was having troubles with the comment.	mohor	8200d 21h	/uart16550/trunk/rtl/verilog/uart_receiver.v
61	overrun signal was moved to separate block because many sequential lsr reads were preventing data from being written to rx fifo. underrun signal was not used and was removed from the project.	mohor	8202d 14h	/uart16550/trunk/rtl/verilog/uart_receiver.v
57	timeout irq must be set regardless of the rda irq (rda irq does not reset the timeout counter).	mohor	8206d 18h	/uart16550/trunk/rtl/verilog/uart_receiver.v
51	Igor fixed break condition bugs	gorban	8209d 09h	/uart16550/trunk/rtl/verilog/uart_receiver.v
50	Bug in LSR[0] is fixed. All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.	gorban	8213d 14h	/uart16550/trunk/rtl/verilog/uart_receiver.v
48	Updated specification documentation. Added full 32-bit data bus interface, now as default. Address is 5-bit wide in 32-bit data bus mode. Added wb_sel_i input to the core. It's used in the 32-bit mode. Added debug interface with two 32-bit read-only registers in 32-bit mode. Bits 5 and 6 of LSR are now only cleared on TX FIFO write. My small test bench is modified to work with 32-bit mode.	gorban	8216d 07h	/uart16550/trunk/rtl/verilog/uart_receiver.v
47	Fixed: timeout and break didn't pay attention to current data format when counting time	gorban	8221d 09h	/uart16550/trunk/rtl/verilog/uart_receiver.v
46	Fixed bug that prevented synthesis in uart_receiver.v	gorban	8222d 06h	/uart16550/trunk/rtl/verilog/uart_receiver.v
45	Lots of fixes: Break condition wasn't handled correctly at all. LSR bits could lose their values. LSR value after reset was wrong. Timing of THRE interrupt signal corrected. LSR bit 0 timing corrected.	gorban	8223d 07h	/uart16550/trunk/rtl/verilog/uart_receiver.v
40	Synthesis bugs fixed. Some other minor changes	gorban	8239d 16h	/uart16550/trunk/rtl/verilog/uart_receiver.v
39	Comments in Slovene language deleted, few small fixes for better work of old tools. IRQs need to be fix.	mohor	8241d 14h	/uart16550/trunk/rtl/verilog/uart_receiver.v
