106 Separated the Timer A defines from the openMSP430 ones.
Added the "dbg_en" port in order to allow a separate reset of the debug interface.
Added the "core_en" port (when cleared, the CPU will stop execution, the dbg_freeze signal will be set and the aclk & smclk will be stopped).
Renamed "per_wen" to "per_we" to prevent confusion with active low signals.
Removed to missing unused flops when the DBG_EN is not defined (thanks to Mihai contribution).		 olivier.girard 4993d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
105 Removed dummy memory read access for the MOV/PUSH/CALL/RETI instructions.
These were not problematic but this is simply cleaner that way.		 olivier.girard 5008d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.		 olivier.girard 5014d 05h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
86 Update serial debug interface test patterns to make them work with all program memory configurations. olivier.girard 5049d 21h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
67 Added 16x16 Hardware Multiplier. olivier.girard 5377d 07h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
53 Fixed the following combinatorial timing loop:
1- irq_detect (omsp_frontend)
2- decode (omsp_frontend)
3- dbg_swbrk (omsp_dbg)
4- halt_flag_set (omsp_dbg)
6- dbg_halt_cmd (omsp_dbg)
7- irq_detect (omsp_frontend)

Without this fix, problem could occur whenever an IRQ request arrives during a software breakpoint instruction fetch.		 olivier.girard 5416d 01h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
34 To avoid potential conflicts with other Verilog modules in bigger projects, the openMSP430 sub-modules have all been renamed with the "omsp_" prefix. olivier.girard 5445d 00h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
33 In order to avoid confusion, the following changes have been implemented to the Verilog code:
- renamed the "rom_*" ports and defines to "pmem_*" (program memory).
- renamed the "ram_*" ports and defines to "dmem_*" (data memory).

In addition, in order to prevent potential conflicts with the Verilog defines of other IPs, a Verilog undefine file has been created.		 olivier.girard 5445d 01h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
23 Renamed the "openMSP430.inc" file to "openMSP430_defines.v" & added the "timescale.v" file.
In order to follow the same structure as other OpenCores projects, the timescale and the defines are now included from within the Verilog files (using the `include construct).		 olivier.girard 5566d 03h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
17 Updated header with SVN info olivier.girard 5591d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
2 Upload complete openMSP430 project to the SVN repository olivier.girard 5626d 22h /openmsp430/trunk/core/rtl/verilog/openMSP430.v
