301 Adding actual task manager files jshamlet 652d 02h /open8_urisc/
300 Adding core task manager assembly jshamlet 652d 03h /open8_urisc/
299 Modified the status_led.vhd to slow down the DIM50PCT signal to 1/32 instead of 1/2 for use with shift-register based discrete LEDs and added the ability to chain the toggle signal to save on resources as well as synchronize the "toggling" jshamlet 654d 03h /open8_urisc/
298 Fixed a long-standing bug in the SBC instruction where the 1 wasn't being added to complete the 2's complement of Rn. This was causing off-by-one errors in subtraction and negating carry only subtractions. jshamlet 655d 05h /open8_urisc/
297 Fixed register map comments jshamlet 945d 13h /open8_urisc/
296 Removed parallel interface from o8_vector_rx.vhd, modified vector_tx.vhd to use a generic for it's seed value, slight formatting change on o8_elapsed_usec.vhd. jshamlet 954d 05h /open8_urisc/
295 Undoing previous revision. UART was fine, bug reporter was not. jshamlet 957d 08h /open8_urisc/
294 Fixed an ancient bug in the parity logic that had the parity inverted. jshamlet 957d 13h /open8_urisc/
293 Fixed formatting issue in o8_sync_serial where tabs were inserted instead of spaces and fixed column spacing as a result (purely cosmetic) jshamlet 976d 13h /open8_urisc/
292 Updated the o8_trig_delay entity by:
1) Added a global interrupt enable,
2) Added the ability to trigger on both the pre- and post-arm trigger input
3) Added the ability to read the external input on offset 7		 jshamlet 1047d 13h /open8_urisc/
291 Added Notepad++ language definition file for the Open8_II ISA jshamlet 1090d 03h /open8_urisc/
290 Added an additional generic "Rotation_Ignores_Carry" that removes the carry logic from the ROL/ROR instructions such that they now rotate 'normally',
Added an alias for PSR_GP4 named PSR_S, as it is now used to switch the function of the RSP instruction. The internal opcode hasn't changed, but it allows assembly code to use PSR_S or BRS/BNS when performing RSP related operations.		 jshamlet 1090d 03h /open8_urisc/
289 Added back the delay for the cursor home command, since it is slow on most Hitachi compatible LCD panels. jshamlet 1107d 14h /open8_urisc/
288 Removed hard-wired R/Wn output and replaced it with a note that the R/Wn line must be tied low either in firmware or on the board. jshamlet 1108d 10h /open8_urisc/
287 Fixed mangled comments and revisioning dates. jshamlet 1109d 09h /open8_urisc/
286 Added initial cut of a "universal" character LCD driver. Allows for adjustment of address setup, enable high, and cycle times. Also has built-in timers for handling timing on certain commands. jshamlet 1109d 09h /open8_urisc/
285 Added checksum byte to vector tx/rx to avoid issues with serial line noise glitching the receiver. Also modified the transmitted to take any generic argument, rather than canned arguments. jshamlet 1116d 12h /open8_urisc/
284 Corrected the vhdl unit name and description for o8_7seg.vhd jshamlet 1230d 00h /open8_urisc/
283 Altered SDLC bitclock check on TX to NOT block when tested by software, but to instead ignore packet write requests if BClk_Okay is low. This allows software to continue checking BClk_Okay in a polling loop. jshamlet 1233d 11h /open8_urisc/
282 Modified the SDLC core transmit states to have consistent naming. jshamlet 1233d 11h /open8_urisc/
