Memory mapping

The "Memory mapping" section, especially the table, seems wrong. Seems the special register just sets the top 8 physical address bits. MMU:20-13 CPU:12-0 . Moritzgedig (talk) 18:09, 7 August 2022 (UTC)[reply]

Here is what is going on: the top three MSb of the 16bit internal address CPU:15-13 select the freely programmable MPR register. The TMAi instruction (01010011) changes the MPR's content. --Moritzgedig (talk) 11:13, 28 August 2022 (UTC)[reply]
