DIV1-0:
Set the division ratio of clocks for internal operations (DIV1-0). Internal operations are in
synchronization with the clock, the frequency of which is divided according to the DIV1-0 setting. When
changing the number of drive raster-rows, adjust the frame frequency too. For details, see “Frame
Frequency Adjustment Function”.
