About 0x3A[1] register of AD9250

Hello.

 

AD9250 is used in the following condition.

 

-SYSREF---one shot

-0x3A=0x0F

 

Once SYSREF is inputted to AD9250, then 0x3A[1] become to 0b.

(I think this is normal behavior)

 

After this, my understanding is that AD9250 would ignore SYSREF signal.

But it seems AD9250 would accept SYSREF signal.

 

Which is expected behavior?

(Which should AD9250 ignore SYSREF or accept SYSREF after 0x3A[1] is self-cleared?)

 

Best regards.

Kikka
