(13) Scan Mode
M37270MF-XXXSP has the bi-scan mode for corresponding to HSYNC
of double speed frequency. In the bi-scan mode, the vertical start
display position and the vertical size is two times as compared with
the normal scan mode. The scan mode is selected by bit 1 of the
OSD control register (refer to Figure 49).
(14) Window Function
This function sets the top and bottom boundary of display limit on a
screen. The window function is valid only in the CC mode. The top
boundary is set by the window H registers 1 and 2. The bottom bound-
ary is set by the window L registers 1 and 2. This function is turned
on and off by bit 5 of the OSD control register (refer to Figure 49).
The structure of the window H registers 1 and 2 is shown in Figure
78, the structure of the window L registers 1 and 2 is shown in Figure
79.
Notes 1: Set values except “0016” and “0116” to the window H regis-
ter 1 when the window H register 2 is “0016.”
2: Set the register value fit for the following condition :
(WH1 + WH2) < (WL1 + WL2)
