bit 6 Display Data Byte Swap
The display pipe fetches 32-bits of data from the display buffer. This bit enables byte 0 and
byte 1 to be swapped, and byte 2 and byte 3 to be swapped, before sending them to the
LCD display. If the Display Data Word Swap bit is also enabled, then the byte order of the
fetched 32-bit data is reversed.

For further information on byte swapping for Big Endian mode, see Section 14, “Big-
Endian Bus Interface” on page 146.
bit 4 Picture-in-Picture Plus (PIP
+
) Window Enable
This bit enables the PIP
+
window within the main window used for the Picture-in-Picture
Plus feature. The location of the PIP
+
window within the landscape window is determined
by the PIP
+
Window X Position registers (REG[84h], REG[85h], REG[8Ch], REG[8Dh])
and PIP
+
Window Y Position registers (REG[88h], REG[89h], REG[90h], REG[91h]).
The PIP
+
window has its own Display Start Address register (REG[7Ch], REG[7Dh],
REG[7Eh]) and Memory Address Offset register (REG[80h], REG[81h]). The PIP
+
win-
dow shares the same color depth and SwivelView
TM
orientation as the main window.
