Question about synchronization between master and slave

Hi,

I am using two chips of ADAS1000-1, one as master and one as slave. But I have question about the synchronization between them.

According to the Example 6 in page 76 of datasheet, I configure slave firstly and then master. If I only send reading frame command to the FRAMES register of master, a sync pulse can be detected from SYNC_GANG pin. But DRDY pin of slave is busy and no data can be read from slave. At the same time, master is working normally.

If I send reading frame command to both of them, all chip can work normally.

Why does the sync pulse seems to be no used if I only send reading frame command to master as Example 6 do?

 

Thanks.
