Updated to route RAM write fault signal and force CPU interrupts to task manager requirements. |

Added a core that specifically supports the task switcher software. It merges o8_int_mgr16 with a wide register, allowing full control of I/O peripherals by the task switcher software. This also allows the task switcher to be enabled for the full 16 I/O write qualification lines, which had previously only been supported in the task data setup. |

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. |
