8.4 Limitations
8.4.1 SwivelView 0° and 180°
In SwivelView 0° and 180°, the main window line address offset register requires the panel
width to be a multiple of 32
÷
bits-per-pixel. If this is not the case, then the main window
line address offset register must be programmed to a longer line which is a multiple of 32
÷
bits-per-pixel. This longer line creates a virtual image where the width is main window
line address offset register
×
32
÷
bits-per-pixel and the main window image must be drawn
right-justified to this virtual width.
Similarly, the sub-window line address offset register requires the sub-window image width
to be a multiple of 32
÷
bits-per-pixel. If this is not the case, then the sub-window line
address offset register must be programmed to a longer line which is a multiple of 32
÷
bits-
per-pixel. This longer line creates a virtual image whose width is sub-window line address
offset register
×
32
÷
bits-per-pixel and the sub-window image must be drawn right-
justified to this virtual width.
8.4.2 SwivelView 90° and 270°
In SwivelView 90° and 270°, the main window line address offset register requires the
panel height to be a multiple of 32
÷
bits-per-pixel. If this is not the case, then the main
window line address offset register must be programmed to a longer line which is a multiple
of 32
÷
bits-per-pixel. This longer line creates a virtual image whose width is main window
line address offset register
×
32
÷
bits-per-pixel and the main window image must be drawn
right-justified to this virtual width.
Similarly, the sub-window line address offset register requires the sub-window image width
to be a multiple of 32
÷
bits-per-pixel. If this is not the case, then the sub-window line
address offset register must be programmed to a longer line which is a multiple of 32
÷
bits-
per-pixel. This longer line creates a virtual image whose width is sub-window line address
offset register
×
32
÷
bits-per-pixel and the sub-window image must be drawn right-
justified to this virtual width.
