Frame Cycle Control (R0Bh)
Figure 15
RTN3-0:
Set the line retrace period (RTN3-0) to be added to raster-row cycles. The raster-row cycle
becomes long according to the number of clocks set at RTN3-0.
DIV1-0:
Set the division ratio of clocks for internal operation (DIV1-0). Internal operations are driven
by clocks which are frequency divided according to the DIV1-0 setting. Frame frequency can be
adjusted along with the line retrace period (RTN3-0). When changing the drive-duty, adjust the frame
frequency. For details, see the Frame Frequency Adjustment Function section.
