Simplified the vector tx/rx system to a single line. An idle detector replaces the attn_req signal. |

Removed extraneous reference to Ints.VEC_Flag from task.s, since it is supposed to be in the init function in test_fn.s. |

More code cleanup on sample projects. SDLC2LCD should now match the Open8_II project model. |

Created a new version of the system timer with 24-bit, 1-uS resolution. The new timer has a much different register interface, so it is now o8_sys_timer_ii. |

Added an initialization constant for the OPEN8_BUS_TYPE record. |

Added a demonstration Open8_cfg.vhd file, which is used to configure the system constants. It also provides a function that makes it easy to merge read buses. |

Finished new Open8 bus record, which now includes the clock, reset and a microsecond tick. The CPU now accepts a clock and pll_locked signal, which it uses to generate the system reset in the bus record. It also contains a simple microsecond counter to feed the usec_tick in the record. This logic was removed from the real time clock and system timer entities, which now use the global version. Bus connections should be dramatically simplified, as only the read logic and interrupts are still run as separate signals. |

Added an OPEN8_BUS_TYPE record to simplify connection to Open8 modules. The CPU now passes and Open8_Bus out, which supplies the bus address, write enable, write data, and read enable. Read data and interrupts are still handled as separate signals, since they are muxed/connected at the next level up. |

Created a modified version of the epoch timer with a 32-bit, 1-uS resolution timer/comparator. |
