Technical Manual
8.3.7. HDOT SCR
While the SCROLL command only allows scrolling by
characters, HDOT SCR allows the screen to be scrolled
horizontally by pixels. HDOT SCR cannot be used on
individual layers.
Figure 20. HDOT SCR parameters
8.3.7.1. D0 to D2
Specifies the number of pixels to scroll. The C/R param-
eter has to be set to one more than the number of
horizontal characters before using HDOT SCR. Smooth
scrolling can be simulated if the controlling microproces-
sor repeatedly issues the HDOT SCR command to the
S1D13305 series. See Section 9.5 for more information
on scrolling the display.

8.4. Drawing Control Commands
8.4.1. CSRW
The 16-bit cursor address register contains the display
memory address of the data at the cursor position as
shown in Figure 22.
Note that the microprocessor cannot directly access the
display memory.
The MREAD and MWRITE commands use the address
in this register.
