I was just turned onto the new DA series and well, wow...they look really impressive! I am having a bit of trouble with the addition of the 2nd TWI bus, specifically 'Dual-Mode', or rather !Dual-Mode. Dual-mode makes sense: 1 bus is for master operations, the other for slave operations.
But what happens when Dual-Mode is inactive? Do we have 2 independent normal TWI interfaces? Or are both busses joined together as if there's a repeater between them? It looks as if the Register Summary of the datasheet is pointing towards the latter, as I don't see MSTATUS0 and MSTATUS1, for instance.
