Flattened block structure to single entity.		 jshamlet 4732d 18h /open8_urisc/trunk/
155 Fixed additional interrupt logic bug,
Optimized several blocks - including ALU, stack, program counter, and data path.		 jshamlet 4733d 13h /open8_urisc/trunk/
154 Fixed problem with missing data path override in interrupt logic. Should resolve issues with processor crashing when an interrupt occurs as a STO instruction is being executed. jshamlet 4738d 16h /open8_urisc/trunk/
153 Fixed bug in interrupt logic that caused stack pointer to increment if interrupt occurred as specific instructions were being decoded,
Fixed bug in interrupt logic where instruction caching would remain enabled during an interrupt, causing improper execution depending on what instruction was in the decode stage as the interrupt is trigered.		 jshamlet 4765d 11h /open8_urisc/trunk/
152 Correct the descriptions for GMSK and SMSK instructions in the Open8 Assembly Language Reference khays 4773d 14h /open8_urisc/trunk/
