PCA9701 PCA9702 SPI explanation and example

Hello,

I am looking at using the PCA9701 in some of my products. I realize the SPI interface appears to be simple, but the explanation of use seems a little vague on the datasheet and I would appreciate a little more detail on how to use this product. 

I would be using it with 12v pull ups, then run through 100k resistors into the inputs. The outputs would be pulled low for "active" states. 

 

Thank you for the time.
