D6 and D7 output "0" when read SAH.
It is possible to set display start address to the extent of 257F

Display start address is established by the writing data to SAH register. Even if only change SAL,
surely set SAH after SAL.
When select 8-bit MPU,start address set in SAL <D7 – D0> + SAH <D5 – D0>.
When select16-bit MPU,start address set in SAL <D7 – D1> + SAH <D5 – D0>.
Even if selecting 16-bit MPU,enable to set display start address in character unit.
In case the display reading data from VRAM start at D<15:12>,set SAL <D0>="0",
and if start at D<7:4>,set SAL <D0>="1". (Refer to Figure-8)
