Alternate SwivelView Mode may be used when the virtual image size of Default SwivelView Mode
cannot be contained in the 80K byte integrated frame buffer. For example, the panel size is 480 320
and the display mode is 4 bit-per-pixel. The minimum virtual image size for Default SwivelView
Mode would be 480 512 which requires 122,880 bytes. Alternate SwivelView Mode requires a
panel size of only 480 320 which needs only 76,800 bytes.
Alternate SwivelView Mode requires the Memory Clock (MCLK) to be at least twice the frequency
of the Pixel Clock (PCLK), i.e. MCLK 2 x PCLK. This makes the power consumption in Alternate
SwivelView Mode higher than in Default SwivelView Mode.
The following figure shows how the programmer sees a 480 320 image and how the image is being
displayed. The application image is written to the S1D13705 in the following sense: A–B–C–D. The
display is refreshed by the S1D13705 in the following sense: B-D-A-C.
