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. |
