Questions about ADAS1000

Hello all,

I have a few questions about ADAS1000.

When the data rate is configured as 2kHz, it means I am getting 2000 frames per second. And each frame contains 11 data words + header, and each word contains 32 bits. So, if I were to scope out the slave select, which goes low at every word, I should see CS go low twelve times in a group. That constitutes a frame. Now, if I am giving the clock from the master, (which I have given above 768kHz as required by the datasheet), I get the data in. However, to confirm that 2000 frames are indeed being sent out, I checked the CS to see how many groups of 12 can I see in a second. However, this doesn't seem to change at all on the scope when I try 2kHz as opposed to 16kHz. The frame rate should become four times, right?

Any suggestions would be welcome. CatherineR Padraic

Thank you!
