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 8202d 13h /uart16550/trunk/rtl/verilog/
59 MSR register fixed. mohor 8205d 10h /uart16550/trunk/rtl/verilog/
58 After reset modem status register MSR should be reset. mohor 8205d 13h /uart16550/trunk/rtl/verilog/
57 timeout irq must be set regardless of the rda irq (rda irq does not reset the
timeout counter).
mohor 8206d 13h /uart16550/trunk/rtl/verilog/
56 thre irq should be cleared only when being source of interrupt. mohor 8206d 13h /uart16550/trunk/rtl/verilog/
55 some synthesis bugs fixed gorban 8207d 01h /uart16550/trunk/rtl/verilog/
54 LSR status bit 0 was not cleared correctly in case of reseting the FCR (rx fifo). mohor 8207d 14h /uart16550/trunk/rtl/verilog/
53 Scratch register define added. mohor 8208d 14h /uart16550/trunk/rtl/verilog/
52 Scratch register added gorban 8209d 03h /uart16550/trunk/rtl/verilog/
51 Igor fixed break condition bugs gorban 8209d 03h /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 8213d 08h /uart16550/trunk/rtl/verilog/
49 committed the debug interface file gorban 8215d 02h /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.
gorban 8216d 02h /uart16550/trunk/rtl/verilog/
47 Fixed: timeout and break didn't pay attention to current data format when counting time gorban 8221d 04h /uart16550/trunk/rtl/verilog/
46 Fixed bug that prevented synthesis in uart_receiver.v gorban 8222d 01h /uart16550/trunk/rtl/verilog/
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 02h /uart16550/trunk/rtl/verilog/
44 fixed more typo bugs gorban 8237d 01h /uart16550/trunk/rtl/verilog/
43 lsr1r error fixed. mohor 8237d 08h /uart16550/trunk/rtl/verilog/
42 ti_int_pnd error fixed. mohor 8237d 08h /uart16550/trunk/rtl/verilog/
41 ti_int_d error fixed. mohor 8237d 08h /uart16550/trunk/rtl/verilog/
