Procedure
1. Overlap part of RAM (H'F880 to H'F8FF) onto the area requiring real-time update (SB1).
2. Perform real-time updates in the overlapping RAM.
3. After finalization of the update data, clear the RAM overlap (by clearing the RAMS and
4. Read the data written in RAM addresses H'F880 to H'F8FF out externally, then program
