Added 24-bit resolution epoch timer / alarm clock |

Corrected issue with CMP and SBC generating an inverted carry flag and added new constants to the package file to simplify interfacing new modules. |

Simplified write data path logic,
Converted RTC to packed BCD,
Corrected several bugs in real time clock component, |

Updated CPU model; Pipelined ALU control signals to improve fMAX, corrected issue with interrupt controller priority not being obeyed, fixed bug in auto-indexing instructions where the upper register wasn't being properly incremented, cleaned up code to make the processor model easier to follow.
Added several useful modules that use the Open8 bus. |

fixed additional issues with range checking on PCREL relocations for open8, added test cases to verify, catch tree up with binutils datestamp 20120301 |

Modified the data path to allow the bus to go idle while waiting for an interrupt. This makes it easier to debug code that uses the WAI instruction, as both Wr_Enable and Rd_Enable go low. |

Added optional generic to specify that the BRK instruction implements a WAit_for_Interrupt (WAI) instruction instead. Logically emulates INT, but without triggering a soft interrupt. Note that the NOP instruction maps to BRK, and will not function correctly if this option is set. |

Optimized for timing,
Flattened block structure to single entity. |

Fixed additional interrupt logic bug,
Optimized several blocks - including ALU, stack, program counter, and data path. |

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. |

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. |
