8.11.13 Window Function
This function sets the top and bottom boundaries for display limits
on a screen. The window function is valid only in the CC mode. The
top boundary is set by the window register 1 and bit 7 of block con-
trol 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 8.11.3).
Window registers 1 and 2 are shown in Figures 8.11.27 and 8.11.28.

8.11.12 Scan mode
The bi-scan mode corresponds to HSYNC of twice as much frequency
as usual. The vertical display position and the vertical dotsize double
compared to the normal scan mode.
In the scan mode, the vertical dot size is set by bit 0 of OSD control
register 2 and the vertical display start position by bit 1, indepen-
dently.

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).
