It does actually say in the datasheet that if the device is in mid write,it will not ack the bus.

And your sure that there's no interaction between devices.

Absolutely sure.
the other ones are 8bit ADC and an remote 8bit IO expander. They can never be masters.
If they have something for me, they have to put a request in form of an interrupt.
the controller then initiates a communications session as master and picks up the data.

I have separate routines that test if the bus is free.
I've used them on other projects, so I'm sure they work.
