130 Fixed POP.B bug (see Bugtracker http://opencores.org/bug,assign,2137 ) olivier.girard 4481d 06h /openmsp430/trunk/core/rtl/
128 Fixed CALL x(SR) bug (see Bugtracker http://opencores.org/bug,view,2111 ) olivier.girard 4557d 07h /openmsp430/trunk/core/rtl/
117 To facilitate commercial adoption of the openMSP430, the core has moved to a modified BSD license. olivier.girard 4733d 08h /openmsp430/trunk/core/rtl/
112 Modified comment. olivier.girard 4766d 07h /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 4767d 07h /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 4823d 06h /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 4838d 06h /openmsp430/trunk/core/rtl/
103 Removed the timescale from all RTL files.
Added possibility to exclude the "includes" statements from the RTL.		 olivier.girard 4843d 13h /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 4844d 06h /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 4844d 07h /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 4856d 08h /openmsp430/trunk/core/rtl/
86 Update serial debug interface test patterns to make them work with all program memory configurations. olivier.girard 4879d 05h /openmsp430/trunk/core/rtl/
85 Diverse RTL cosmetic updates. olivier.girard 4879d 07h /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 4884d 08h /openmsp430/trunk/core/rtl/
79 Update the GPIO peripheral to fix a potential synchronization issue. olivier.girard 4945d 08h /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 5032d 08h /openmsp430/trunk/core/rtl/
72 Expand configurability options of the program and data memory sizes. olivier.girard 5059d 09h /openmsp430/trunk/core/rtl/
67 Added 16x16 Hardware Multiplier. olivier.girard 5206d 16h /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 5206d 20h /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 5238d 06h /openmsp430/trunk/core/rtl/
