Merge pull request #1001 from TomHarte/AmigaReadWrite 
Ensures Chipset reads can map to writes and vice versa.

348840a2aa It's probably a net detriment to use a template in this scenario. 2021-12-19 16:31:44 -05:00

f118891970 Breaks Chipset::perform into read and write. 
This allows each to call the other when a read occurs of a write-only address, and vice versa.

f3ec7d54bb Clarifies wait-for-CPU-slot semantics. 
Big bonus: this guarantees `advance_dma`s will be called at most once per output cycle, even if they return `false`.
