IQAN-XS2 VIN/DIN. Are these switched in groups of 4? Pins are in two groups. There is a comment to the side, but nothing as explicit as I usually see in manuals.

There are two types of DIN on the XS2 and XA2 modules, the first type that is shared with VIN pins, and are designed as dedicated inputs.
The second type is sharing pins with the low side switches for XA2 CRET, and because of that they have an internal diode to the highside switch, and one has to be cautious about the risk of reverse feed.
That is what the note about the second group of digital inputs is for.
