image seen by programmer
= image in display buffer
The following figure shows how the programmer sees a 480x320 landscape 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: D-C-B-A.
Enable
Set SwivelView™ Mode Select bits (REG[71h] bits 1:0) to 10.
Display Start Address
The display refresh circuitry starts at pixel “D”, therefore the Main Window Display Start
Address registers (REG[74h], REG[75h], REG[76h]) must be programmed with the
address of pixel “D”. To calculate the value of the address of pixel “D” use the following
formula (assumes 8 bpp color depth).
Main Window Display Start Address bits 16:0

= ((image address + (offset x (panel height - 1) + panel width) x bpp ÷ 8) ÷ 4) - 1
= ((0 + (480 pixels x 319 pixels + 480 pixels) x 8 bpp ÷ 8) ÷ 4) - 1
