>From my interpretation of things, there's nothing explicitly preventing both a pending start and stop - more that the interrupt is very likely to have been serviced between those two events on the kind of speeds we would see on the i2c bus. I guess we could try (temporarily) masking the irq on real hardware and see what happens? :D Cheers, Jeremy
