frequency of the Pixel Clock (PCLK), i.e. MCLK ≥ 1.25PCLK.
The following figure shows how the programmer sees a 320x480 portrait image and how
the image is being displayed. The application image is written to the S1D13706 in the
following sense: A–B–C–D. The display is refreshed by the S1D13706 in the following
sense: C-A-D-B.
