S1D13700 Technical Manual
(1) Cursor register function
(2) Direction of cursor movement
(3) Cursor display layer
Cursor
The cursor register in the S1D13700 serves dual purposes as a cursor address register required to display
the cursor on the screen, and as an address pointer to be referenced when accessing display memory.
To access any display memory area other than the screen while displaying the cursor, the cursor address
must be preset before attempting such access and restored to the previous value after access is completed.
Note: The cursor will disappear if the cursor address is moved to any area other than the screen
The cursor address is automatically shifted in the specified direction from the value preset by a memory
control command.
Although the S1D13700 can display up to three overlaid layers, the cursor can be displayed in only one of
those layers. In other words, the cursor-attribute layer (or layer in which the cursor can be displayed) is:
The cursor will not appear if moved to other than those cursor-attribute layers. If the cursor must be
displayed, change the layers or move the cursor-attribute layer to the cursor address location.
Although the cursor is generally displayed in text mode, the S1D13700 can also display a dummy cursor
in graphics mode. This is accomplished by using the graphics screen as a display plane while not
displaying the text screen, but using it to only generate addresses for cursor control.
