8.3.4 SwivelView 270°
Figure 8-5: Picture-in-Picture Plus with SwivelView 270° enabled
SwivelView 270
° is a mode in which both the main and PIP
+
windows are rotated 270°
counter-clockwise when shown on the panel. The images for each window are typically
placed consecutively, with the main window image starting at address 0 and followed by
the PIP
+
window image. In addition, both images must start at addresses which are dword-
aligned (the last two bits of the starting address must be 0).
Note
It is possible to use the same image for both the main window and PIP
+
window. To do
so, set the PIP
+
Line Address Offset register (REG[81h],REG[80h]) to the same value
as the Main Window Line Address Offset register (REG[79h],REG[78h]).
