67 Missing declaration of rf_push_q fixed. mohor 8210d 12h /uart16550/tags/rel_3/rtl/
66 rx push changed to be only one cycle wide. mohor 8210d 12h /uart16550/tags/rel_3/rtl/
65 Warnings fixed (unused signals removed). mohor 8211d 17h /uart16550/tags/rel_3/rtl/
64 Warnings cleared. mohor 8211d 17h /uart16550/tags/rel_3/rtl/
63 Synplicity was having troubles with the comment. mohor 8211d 18h /uart16550/tags/rel_3/rtl/
62 Bug that was entered in the last update fixed (rx state machine). mohor 8212d 16h /uart16550/tags/rel_3/rtl/
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 8213d 11h /uart16550/tags/rel_3/rtl/
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 8213d 15h /uart16550/tags/rel_3/rtl/
59 MSR register fixed. mohor 8216d 12h /uart16550/tags/rel_3/rtl/
58 After reset modem status register MSR should be reset. mohor 8216d 15h /uart16550/tags/rel_3/rtl/
57 timeout irq must be set regardless of the rda irq (rda irq does not reset the
timeout counter).
mohor 8217d 15h /uart16550/tags/rel_3/rtl/
56 thre irq should be cleared only when being source of interrupt. mohor 8217d 15h /uart16550/tags/rel_3/rtl/
55 some synthesis bugs fixed gorban 8218d 03h /uart16550/tags/rel_3/rtl/
54 LSR status bit 0 was not cleared correctly in case of reseting the FCR (rx fifo). mohor 8218d 16h /uart16550/tags/rel_3/rtl/
53 Scratch register define added. mohor 8219d 16h /uart16550/tags/rel_3/rtl/
52 Scratch register added gorban 8220d 05h /uart16550/tags/rel_3/rtl/
51 Igor fixed break condition bugs gorban 8220d 05h /uart16550/tags/rel_3/rtl/
50 Bug in LSR[0] is fixed.
All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
gorban 8224d 10h /uart16550/tags/rel_3/rtl/
49 committed the debug interface file gorban 8226d 04h /uart16550/tags/rel_3/rtl/
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.
