The ALTMEMPHY leveling sequencer during calibration writes to the following locations:-Bank 0, 1, and 3
Bank 0 is written to for the block training pattern and clock cycle calibration.
Bank 1 is written to for write deskew (DQ).
Bank 2 is written to for write deskew (DM).
For each bank, only row 1 is accessed. The number of columns accessed can vary, but you should avoid writing to all columns in these banks and row 1.
