128 Fixed CALL x(SR) bug (see Bugtracker http://opencores.org/bug,view,2111 ) olivier.girard 4551d 09h /openmsp430/trunk/core/rtl/
117 To facilitate commercial adoption of the openMSP430, the core has moved to a modified BSD license. olivier.girard 4727d 11h /openmsp430/trunk/core/rtl/
112 Modified comment. olivier.girard 4760d 09h /openmsp430/trunk/core/rtl/
111 Re-organized the "openMSP430_defines.v" file.
Re-defined the CPU_ID register of the debug interface (in particular to support custom user versioning).
Added RTL configuration possibility to expand the peripheral address space from 512B (0x0000 to 0x0200) to up to 32kB (0x0000 to 0x8000).
As a consequence the per_addr bus width goes from 8 to 14 bits and the peripherals address decoders have been updated accordingly.		 olivier.girard 4761d 09h /openmsp430/trunk/core/rtl/
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 4817d 08h /openmsp430/trunk/core/rtl/
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 4832d 09h /openmsp430/trunk/core/rtl/
103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.		 olivier.girard 4837d 15h /openmsp430/trunk/core/rtl/
102 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+		 olivier.girard 4838d 08h /openmsp430/trunk/core/rtl/
101 Cosmetic change in order to prevent an X propagation whenever executing a byte instruction with an uninitialized memory location as source. olivier.girard 4838d 10h /openmsp430/trunk/core/rtl/
91 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.		 olivier.girard 4850d 10h /openmsp430/trunk/core/rtl/
86 Update serial debug interface test patterns to make them work with all program memory configurations. olivier.girard 4873d 07h /openmsp430/trunk/core/rtl/
85 Diverse RTL cosmetic updates. olivier.girard 4873d 09h /openmsp430/trunk/core/rtl/
84 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.		 olivier.girard 4878d 10h /openmsp430/trunk/core/rtl/
79 Update the GPIO peripheral to fix a potential synchronization issue. olivier.girard 4939d 10h /openmsp430/trunk/core/rtl/
74 Update serial debug interface to support memories with a size which is not a power of 2.
Update the software tools accordingly.		 olivier.girard 5026d 10h /openmsp430/trunk/core/rtl/
72 Expand configurability options of the program and data memory sizes. olivier.girard 5053d 11h /openmsp430/trunk/core/rtl/
67 Added 16x16 Hardware Multiplier. olivier.girard 5200d 18h /openmsp430/trunk/core/rtl/
66 The peripheral templates are now under BSD license.
Developers of new peripherals based on these templates won't have to disclose their code.		 olivier.girard 5200d 22h /openmsp430/trunk/core/rtl/
60 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 ).		 olivier.girard 5232d 09h /openmsp430/trunk/core/rtl/
57 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.		 olivier.girard 5234d 07h /openmsp430/trunk/core/rtl/
