hello i have a question about adv212. My system is designed to use fpga to access adv212. Somtimes the first write operation dose not work. When fpga set cs and we signal to 0,the ack signal of adv212 dose not become 0. I have tryed several adv212,not all of this has this problem.

1.In what situatuon this can happen?

2.When power up,adv212 has how many mode,in what mode can cause this problem?

3.when the adv212 will read the cfg1 and cfg2?after powup or in its reset?

I have two pictures will show more.

Thank you very much!
