S1D13700 Technical Manual
Although the screen can be scrolled left or right only in units of characters using the SCROLL command
alone, the combined use of this command allows the screen to be scrolled in units of dots. The scrolling on
individual layers, however, cannot be controlled.
This command defines the number of dots to be shifted from the character origin.

The C/R value must be set to one more than the number of display characters before using
HDOT SCR to scroll the screen in units of dots. Smooth scrolling (dotwise scrolling) is possible
when the MPU resends the HDOT SCR command to the S1D13700 at given time intervals for
setting the number of dots to be shifted from the character origin.
Note: See Section 4.1.7 “Scrolling” on page 65, for more information about this
