Rev Log message Author Age Path
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 1280d 22h /open8_urisc
289 Added back the delay for the cursor home command, since it is slow on most Hitachi compatible LCD panels. jshamlet 1298d 09h /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 1299d 05h /open8_urisc
287 Fixed mangled comments and revisioning dates. jshamlet 1300d 04h /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 1300d 05h /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 1307d 08h /open8_urisc
284 Corrected the vhdl unit name and description for o8_7seg.vhd jshamlet 1420d 19h /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 1424d 06h /open8_urisc
282 Modified the SDLC core transmit states to have consistent naming. jshamlet 1424d 07h /open8_urisc
281 Added pre-initialization to the dual-port RAM signals. jshamlet 1424d 09h /open8_urisc
280 Got rid of silly aliases that connected the dual-port memory and the arbitration logic. jshamlet 1424d 10h /open8_urisc
279 More comment cleanup jshamlet 1425d 07h /open8_urisc
278 Flattened the SDLC interface to fewer files and eliminated the package file. jshamlet 1426d 01h /open8_urisc
277 Fixed documentation errors related to flags. The UPP ALU instruction only alters the C flag, not the Z or N flags. This implies that using indexed loads or stores with auto post-increment will potentially alter the C flag. jshamlet 1426d 07h /open8_urisc
276 More comment fixes jshamlet 1461d 04h /open8_urisc
275 Fixed a minor comment error. jshamlet 1462d 22h /open8_urisc
274 Updated comments with more corrections jshamlet 1463d 05h /open8_urisc
273 Updated comments with corrections jshamlet 1463d 06h /open8_urisc
272 Updated the HTML documentation to reflect the removed generic. jshamlet 1473d 06h /open8_urisc
271 Removed deleted generic define. jshamlet 1473d 06h /open8_urisc
