Hi there,

 

I'm reading an application note AN-1077.

And I have 2 things I don't understand it.

Please give me some advice.

#1,

According Fig 5, there is a wait time for 1.1ms.
What is the reason for this wait time?

 

#2,

About Figure 7. Data Read Timing Sequence for 4-Wire SPI Connection,
It look like  that this figure show that INT1PIN is clear when SDI command( Read to ADAXs resisters)  transmition is completed.

Is INT1 PIN become clear automatically?.Please tell me this behavor.

I'd like to make sure that how long innterupt signal remain and how to clear interupt from the HOST controler.

 

Best,

Tarzan
