106 New directory structure. root 5539d 01h /uart16550/tags/asyst_3/
77 This commit was manufactured by cvs2svn to create tag 'asyst_3'. 8114d 18h /tags/asyst_3/
75 Endian define added. Big Byte Endian is selected by default. mohor 8114d 18h /trunk/
74 tf_overrun signal was disabled since it was not used gorban 8119d 19h /trunk/
73 major bug in 32-bit mode that prevented register access fixed. gorban 8126d 19h /trunk/
72 UART PHY added. Files are fully operational, working on HW. mohor 8140d 02h /trunk/
71 Removed confusing comment gorban 8151d 15h /trunk/
70 tf_pop was too wide. Now it is only 1 clk cycle width. mohor 8156d 23h /trunk/
69 More than one character was stored in case of break. End of the break
was not detected correctly.
mohor 8165d 14h /trunk/
68 lsr[7] was not showing overrun errors. mohor 8168d 21h /trunk/
67 Missing declaration of rf_push_q fixed. mohor 8175d 21h /trunk/
66 rx push changed to be only one cycle wide. mohor 8175d 21h /trunk/
65 Warnings fixed (unused signals removed). mohor 8177d 02h /trunk/
64 Warnings cleared. mohor 8177d 03h /trunk/
63 Synplicity was having troubles with the comment. mohor 8177d 03h /trunk/
62 Bug that was entered in the last update fixed (rx state machine). mohor 8178d 02h /trunk/
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 8178d 20h /trunk/
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 8179d 01h /trunk/
59 MSR register fixed. mohor 8181d 22h /trunk/
58 After reset modem status register MSR should be reset. mohor 8182d 01h /trunk/
57 timeout irq must be set regardless of the rda irq (rda irq does not reset the
timeout counter).
mohor 8183d 00h /trunk/
56 thre irq should be cleared only when being source of interrupt. mohor 8183d 01h /trunk/
55 some synthesis bugs fixed gorban 8183d 13h /trunk/
54 LSR status bit 0 was not cleared correctly in case of reseting the FCR (rx fifo). mohor 8184d 02h /trunk/
53 Scratch register define added. mohor 8185d 02h /trunk/
52 Scratch register added gorban 8185d 15h /trunk/
51 Igor fixed break condition bugs gorban 8185d 15h /trunk/
50 Bug in LSR[0] is fixed.
All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
gorban 8189d 20h /trunk/
49 committed the debug interface file gorban 8191d 14h /trunk/
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.
