117 To facilitate commercial adoption of the openMSP430, the core has moved to a modified BSD license. olivier.girard 4735d 18h /openmsp430/trunk/core/
115 Add linker script example. olivier.girard 4760d 18h /openmsp430/trunk/core/
112 Modified comment. olivier.girard 4768d 17h /openmsp430/trunk/core/
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 4769d 17h /openmsp430/trunk/core/
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 4825d 15h /openmsp430/trunk/core/
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 4840d 16h /openmsp430/trunk/core/
103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.		 olivier.girard 4845d 22h /openmsp430/trunk/core/
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 4846d 15h /openmsp430/trunk/core/
101 Cosmetic change in order to prevent an X propagation whenever executing a byte instruction with an uninitialized memory location as source. olivier.girard 4846d 17h /openmsp430/trunk/core/
99 Small fix for CVER simulator support. olivier.girard 4850d 17h /openmsp430/trunk/core/
98 Added support for VCS verilog simulator.
VPD and TRN waveforms can now be generated.		 olivier.girard 4850d 17h /openmsp430/trunk/core/
95 Update some test patterns for the additional simulator supports. olivier.girard 4854d 17h /openmsp430/trunk/core/
94 Thanks to Mihai-Costin Manolescu's contribution, the simulation scripts now support the following simulators:
- Icarus Verilog
- Cver
- Verilog-XL
- NCVerilog
- Modelsim		 olivier.girard 4854d 17h /openmsp430/trunk/core/
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 4858d 17h /openmsp430/trunk/core/
86 Update serial debug interface test patterns to make them work with all program memory configurations. olivier.girard 4881d 14h /openmsp430/trunk/core/
85 Diverse RTL cosmetic updates. olivier.girard 4881d 16h /openmsp430/trunk/core/
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 4886d 17h /openmsp430/trunk/core/
80 Create initial version of the Actel FPGA implementation example. olivier.girard 4936d 00h /openmsp430/trunk/core/
79 Update the GPIO peripheral to fix a potential synchronization issue. olivier.girard 4947d 18h /openmsp430/trunk/core/
76 Add possibility to simulate C code within the "core" environment. olivier.girard 4952d 16h /openmsp430/trunk/core/
