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+ |

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. |

Update SRAM model in the core testbench to prevent the IEEE warning when running simulations.
Update watchdog to fix NMI synchronisation problem.
Add synchronizers for the PUC signal in the debug interface. |

The peripheral templates are now under BSD license.
Developers of new peripherals based on these templates won't have to disclose their code. |

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). |
