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?
