67 Missing declaration of rf_push_q fixed. mohor 8207d 15h /uart16550/trunk/rtl/verilog/
66 rx push changed to be only one cycle wide. mohor 8207d 15h /uart16550/trunk/rtl/verilog/
65 Warnings fixed (unused signals removed). mohor 8208d 20h /uart16550/trunk/rtl/verilog/
64 Warnings cleared. mohor 8208d 21h /uart16550/trunk/rtl/verilog/
63 Synplicity was having troubles with the comment. mohor 8208d 21h /uart16550/trunk/rtl/verilog/
62 Bug that was entered in the last update fixed (rx state machine). mohor 8209d 20h /uart16550/trunk/rtl/verilog/
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 8210d 14h /uart16550/trunk/rtl/verilog/
60 Things related to msr register changed. After THRE IRQ occurs, and one
character is written to the transmit fifo, the detection of the THRE bit in the
LSR is delayed for one character time.
mohor 8210d 19h /uart16550/trunk/rtl/verilog/
59 MSR register fixed. mohor 8213d 15h /uart16550/trunk/rtl/verilog/
58 After reset modem status register MSR should be reset. mohor 8213d 19h /uart16550/trunk/rtl/verilog/
57 timeout irq must be set regardless of the rda irq (rda irq does not reset the
timeout counter).
mohor 8214d 18h /uart16550/trunk/rtl/verilog/
56 thre irq should be cleared only when being source of interrupt. mohor 8214d 19h /uart16550/trunk/rtl/verilog/
55 some synthesis bugs fixed gorban 8215d 07h /uart16550/trunk/rtl/verilog/
54 LSR status bit 0 was not cleared correctly in case of reseting the FCR (rx fifo). mohor 8215d 20h /uart16550/trunk/rtl/verilog/
53 Scratch register define added. mohor 8216d 20h /uart16550/trunk/rtl/verilog/
52 Scratch register added gorban 8217d 09h /uart16550/trunk/rtl/verilog/
51 Igor fixed break condition bugs gorban 8217d 09h /uart16550/trunk/rtl/verilog/
50 Bug in LSR[0] is fixed.
All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
gorban 8221d 14h /uart16550/trunk/rtl/verilog/
49 committed the debug interface file gorban 8223d 08h /uart16550/trunk/rtl/verilog/
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.
