ADE7566 can't work

Hi Sir

I am debuging ADE7566 target board, when power up, I find the 32.768K OSC can't work,

But I re-power up, ADE7566 can be normal.

And then re-ON-OFF many times, ADE7566 and there will be no abnormal phenomenon, why the first power-up ADE7566 can not work?

I am currently using the Crystal ESR typ 40K ohm, but if I use Crystal ESR less  than on the data sheet specifications,will it cause an impact?



Why do you need MIN ESR requirements, and my Crystal vendor thinks it should be as small as possible?
