If no text screen is displayed, only a bar cursor can be displayed at the cursor address.
If the first layer is a mixed text and graphics screen and the cursor shape is set to a block
cursor, the S1D13700F02 automatically decides which cursor shape to display. On the text
screen it displays a block cursor, and on the graphics screen, a bar cursor.
The S1D13700F02 supports virtual screens that are larger than the physical size of the LCD
panel address range (C/R), REG[03h] bits 7-0. A layer of the S1D13700F02 can be
considered as a window into the larger virtual screen held in display memory. This window
can be divided into two blocks, with each block able to display a different portion of the
virtual screen.
For example, this allows one block to dynamically scroll through a data area while the other
block is used as a status message display area.
