Modified the Open8 version of the multi-channel roll average code to have separate interrupt enables for average and flush operations. Note that the flush status bit should be checked by software prior to use if the Autoflush_On_Reset generic is set TRUE.
Also adding the ROMTAPE entity, which acts as a serial-access ROM for storing strings, arrays, etc. in order to alleviate pressure on the primary program ROM. It is intended for use with loops that load fixed content from ROM. |

More code cleanup and comments,
Removed INT_VECTOR_n constants, as they are superfluous. There are no reasonable situations in which the constants would be altered. |

Added optional DACadv signal to advance the PWM engine using an external signal. This is used to synchronize the DAC with other DACs or for streaming multiple streams across a high-speed serial link. |

Modified the status_led.vhd to slow down the DIM50PCT signal to 1/32 instead of 1/2 for use with shift-register based discrete LEDs and added the ability to chain the toggle signal to save on resources as well as synchronize the "toggling" |

Fixed a long-standing bug in the SBC instruction where the 1 wasn't being added to complete the 2's complement of Rn. This was causing off-by-one errors in subtraction and negating carry only subtractions. |

Updated the o8_trig_delay entity by:
1) Added a global interrupt enable,
2) Added the ability to trigger on both the pre- and post-arm trigger input
3) Added the ability to read the external input on offset 7 |

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. |
