CR/CB/CG: The window cursor color can be specified. Red, blue, green, white, black, or any combination
color can be displayed. However, the cursor color cannot be controlled by the grayscale. For details, see the
Color Window Cursor Control section.

Grayscale and Blink Synchronization (R09h)
Initializes the blink and frame counters, which control the blink cycle and grayscale generation, respectively.

Vertical Scroll Control (R11h)
VL16–11: Specify the display-start raster-row at the 1st screen display for vertical smooth scrolling. Any
raster-row from the first to 80th can be selected. After the 80th raster-row is displayed, the display restarts
from the first raster-row. The display-start raster-row (VL16-10) is valid only when VLE1 = 1. The raster-
row display is fixed when VLE1 = 0. (VLE1 is the 1st-screen vertical-scroll enable bit.)
VL26–20: Specify the display-start raster-row at the 2nd screen display. The display-start raster-row (VL26-
20) is valid only when VLE2 = 1. The raster-row display is fixed when VLE2 = 0. (VLE2 is the 2nd-screen
vertical-scroll enable bit.) The vertical scroll for the 1st and 2nd screens can be independently set.
