76 This commit was manufactured by cvs2svn to create tag 'asyst_2'. 8125d 12h /
75 Endian define added. Big Byte Endian is selected by default. mohor 8125d 12h /
74 tf_overrun signal was disabled since it was not used gorban 8130d 13h /
73 major bug in 32-bit mode that prevented register access fixed. gorban 8137d 13h /
72 UART PHY added. Files are fully operational, working on HW. mohor 8150d 20h /
71 Removed confusing comment gorban 8162d 09h /
70 tf_pop was too wide. Now it is only 1 clk cycle width. mohor 8167d 17h /
69 More than one character was stored in case of break. End of the break
was not detected correctly.
mohor 8176d 08h /
68 lsr[7] was not showing overrun errors. mohor 8179d 16h /
67 Missing declaration of rf_push_q fixed. mohor 8186d 15h /
66 rx push changed to be only one cycle wide. mohor 8186d 16h /
65 Warnings fixed (unused signals removed). mohor 8187d 20h /
64 Warnings cleared. mohor 8187d 21h /
63 Synplicity was having troubles with the comment. mohor 8187d 21h /
62 Bug that was entered in the last update fixed (rx state machine). mohor 8188d 20h /
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 8189d 14h /
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 8189d 19h /
59 MSR register fixed. mohor 8192d 16h /
58 After reset modem status register MSR should be reset. mohor 8192d 19h /
57 timeout irq must be set regardless of the rda irq (rda irq does not reset the
timeout counter).
mohor 8193d 18h /
56 thre irq should be cleared only when being source of interrupt. mohor 8193d 19h /
55 some synthesis bugs fixed gorban 8194d 07h /
54 LSR status bit 0 was not cleared correctly in case of reseting the FCR (rx fifo). mohor 8194d 20h /
53 Scratch register define added. mohor 8195d 20h /
52 Scratch register added gorban 8196d 09h /
51 Igor fixed break condition bugs gorban 8196d 09h /
50 Bug in LSR[0] is fixed.
All WISHBONE signals are now sampled, so another wait-state is introduced on all transfers.
gorban 8200d 14h /
49 committed the debug interface file gorban 8202d 08h /
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 8203d 07h /
47 Fixed: timeout and break didn't pay attention to current data format when counting time gorban 8208d 09h /
