264 Updated comments jshamlet 1462d 07h /open8_urisc/trunk
263 Fixed a very old bug in the CPU core where autoincrements weren't affecting the upper register in the pair, causing it to loop around the lower 256 bytes. This only affected LDX/LDO, as the proper ALU signals were being generated in STO/STX and UPP. Wow, that bug has been in there for AGES.

Also separated the SDLC TX and RX interrupts so that they could be handled separately.		 jshamlet 1462d 08h /open8_urisc/trunk
262 Added comments to LCD controllers - specifically that reading either register 0 or 1 will return the ready status. This code was already present, but not mentioned in the register map. jshamlet 1471d 11h /open8_urisc/trunk
261 Increased delay timer to 7 bits for button press detection. jshamlet 1478d 11h /open8_urisc/trunk
260 Added missing comments for Sequential_Interrupts generic, as well as comments explaining portions of the CPU operations. jshamlet 1491d 10h /open8_urisc/trunk
259 Fixed issue where Write_Fault wasn't defaulting to '0' when Write_Protect was set to FALSE,
Added a pulse interval measurement entity,
Fixed comments.		 jshamlet 1491d 12h /open8_urisc/trunk
258 Fixed write bug in o8_ltc2355_2p.vhd, added a newer Open8_cfg.vhd, and the sys_tick.vhd utility entity. jshamlet 1492d 09h /open8_urisc/trunk
257 Fixed misnamed signal in o8_7seg.vhd and added a replacement switch interface that handles both static and pushbutton switches. jshamlet 1492d 10h /open8_urisc/trunk
256 Removed unused generic from the status_led.vhd and cleaned up comments on the CPU jshamlet 1492d 11h /open8_urisc/trunk
255 Modified code to make ModelSim happy (It didn't like the generate blocks for some reason). Also added a block describing the new generic. jshamlet 1492d 16h /open8_urisc/trunk
