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.

The memory area is divided equally
regardless of whether bitmap is registered or
not.
If no bitmap is registered, the memory is
divided equally.
If no bitmap is registered, the memory is
divided equally.

If a bitmap is registered, the area of the
bitmap is kept. The rest memory area is
divided equally.
The area of the bitmap is limited to the
bitmap size. The rest memory area is
divided equally.

After divided, if the area of the bitmap is
smaller than the bitmap size, the bitmap will
be deleted.
After divided, if the number of sections
becomes smaller, the registered bitmap may
be deleted.
The start position of the area in which bitmap
is registered is not changed. The area just
before the registered bitmap is not resized.
After divided, if the area of the bitmap is
enough for the bitmap, the bitmap will not be
deleted.
