Although the cursor is normally displayed for character data, the S1D13700F01 may also
display a dummy cursor for graphical characters. This is only possible if a graphics screen
is displayed, the text screen is turned off, and the microprocessor generates the cursor
control address.
For example, if Chinese characters are displayed on a graphics screen, the cursor address is
set to the second screen block in order to write the “graphics” display data. However, the
cursor is not displayed. To display the cursor, the cursor address must be set to an address
within the blank text screen block.
Since the automatic cursor increment is in address units, not character units, the controlling
microprocessor must set the Cursor Write register (REG[1Ch] - REG[1Dh]) when moving
the cursor over the graphical characters.
D (REG[09h] bit 0) = 1
FC1 (REG[0Ah] bit 1) = 0
FC0 (REG[0Ah] bit 0) = 1
FP1 (REG[0Ah] bit 3) = 0
FP0 (REG[0Ah] bit 2) = 0
FP3 (REG[0Ah] bit 5) = 0
FP2 (REG[0Ah] bit 4) = 1
