Hi, 

 

I have a question about ZQ calibration timing.

When ZQ calibration start at the first time after MPZQHWCTRL resister set.

1. Does it start right after ZQ_MODE[1:0] register set other than 0x00?

2. Does it need to set ZQ_HW_FOR only for start trigger at the first time?

3. Any other register bit setting need to start other than above?

 

Best Regards,

Sugiyama
