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). |

Removed dummy memory read access for the MOV/PUSH/CALL/RETI instructions.
These were not problematic but this is simply cleaner that way. |

Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL. |

Fixed bug reported by Mihai ( http://opencores.org/bug,view,1955 ).
The following PUSH instructions are now working as expected:
- indexed mode: PUSH x(R1)
- indirect register mode: PUSH @R1
- indirect autoincrement: PUSH @R1+ |

Cosmetic change in order to prevent an X propagation whenever executing a byte instruction with an uninitialized memory location as source. |

Fixed bug when an IRQ arrives while CPU is halted through the serial debug interface.
This bug is CRITICAL for people using working with interrupts and the Serial Debug Interface. |

The peripheral templates are now under BSD license.

Cleanup of the PC (R0) generation logic.
Formal equivalence was shown between the new and old code with Synopsys' Formality (to make sure that nothing has been broken :-P ). |

Update design to exclude the range mode from the debug hardware breakpoint units. As this feature is not used by GDB, it has been disabled in order to improve the timings and save a bit of area/utilisation.
Note that if required, this feature can be re-enabled through the `HWBRK_RANGE define located in the "openMSP430_defines.v" file. |

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. |

To avoid potential conflicts with other Verilog modules in bigger projects, the openMSP430 sub-modules have all been renamed with the "omsp_" prefix. |

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. |

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). |
