I have a question AD7091R-8.
This is how to set the channel register.
Which of the following two is correct? Or are they different?
① First set the Address (including R / W). The lower 10 bits are set to '0' → Next Channel Register is set. For example, 'FF' when all channels are used
That is, two accesses are required
② Address containing R / W in the upper 6 bits, lower 8 bits as FF.
In other words, it is OK with one access
