Step 1: Direct access to config memory.
Step 2: Configure device for multi-panel writes.
Step 3: Direct access to code memory.
Step 4: Load write buffer for Panel 1.
Step 5: Repeat for Panel 2.
Step 6: Repeat for all but the last panel (N – 1).
Step 7: Load write buffer for last panel.
To continue writing data, repeat steps 2 through 5, where the Address Pointer is incremented by 8 in each panel at each iteration of
the loop.
