8.10.13 Window Function
This function sets the top and bottom boundaries for display limits
on a screen. The window function is valid only in the OSD1 mode.
The top boundary is set by the window register 1 and bit 7 of block
control register 1. The bottom boundary is set by window register 1
and bit 7 of block control register 2. This function is turned on and off
by bit 2 of the OSD control register (refer to Figure 8.10.3).
Window registers 1 and 2 are shown in Figures 8.10.27 and 8.10.28.

8.10.12 Scan mode
The Bi-scan mode corresponds to HSYNC of twice as much frequency
as usual. The vertical display position and the vertical dot size double
compared to the normal scan mode. Scan mode can be set the ver-
tical dot size in bit 0 of OSD control register 2, and the vertical dis-
play start position in bit 1, independently .

The setting value per one step of the top and bottom window borders
can be switched to either 1TH or 2TH by setting “0” or “1” to bit 1 of
OSD control register 2 (address 02DB16).
