8.16.8 Dividing memory area [DIVIDE MEMORY]

You can register up to four bitmaps within the available memory area by dividing the memory. You can select
one of three dividing modes or specify the size you want to divide manually.
Memory areas are controlled by blocks. 1 block = 65,536 bytes; 128 blocks = 8,388,608 bytes in total.
