*2: Horizontal display position
The horizontal display position is several dot clocks (see "18.2.4.1 Screen Display Position
Offset") after the sync pulse significant edge (controlled by bit HE of command 13-1) of the
horizontal sync signal (HSYNC pin input signal).
Note:
Display output of display signal outputs (RGB, VOB1, and VOB2) are off during the specified period
after input of the sync pulse of the vertical sync signal (VSYNC pin input signal) and the sync pulse
of the horizontal sync signal (HSYNC pin input signal).
■ Display Position Control of Sprite Characters
The ODSC controls the display start positions of a sprite character and its trimming.
❍ Sprite character vertical display position: Sprite character control 4 (command 9-0), Bits
SY9 to SY0
Set the vertical display position relative to the sync pulse of the vertical sync signal (VSYNC pin
input signal).
The position can be set between 0 and 2046 dots in 2-dot units.
❍ Sprite character horizontal display position: Sprite character control 5 (command 9-1), Bits
SX10 to SX0
Set the horizontal display position relative to the sync pulse of the horizontal sync signal (HSYNC
pin input signal).
The position can be set between 0 and 3070 dots in 2-dot units.
Figure 18.2-9 shows the display position of sprite characters.

*1: Horizontal display position
The vertical display position reference is the same as on the main screen; it is 1H after the sync
pulse signal of the vertical sync signal (VSYNC pin input signal). See Figure 18.2-5.
