SwivelView Mode
Set SwivelView Mode Select bits (REG[71h] bits 1:0) to 01.
Display Start Address
The display refresh circuitry starts at pixel “B”, therefore the Main Window Display Start
Address registers (REG[74h], REG[75h], REG[76h]) must be programmed with the
address of pixel “B”. To calculate the value of the address of pixel “B” use the following
formula (assumes 8 bpp color depth).
Main Window Display Start Address bits 16:0
= ((image address + (panel height x bpp
÷
8))
÷
4) - 1
= ((0 + (320 pixels x 8 bpp
÷
8))
÷
4) -1
= 79 (4Fh)
Line Address Offset
The Main Window Line Address Offset registers (REG[78h], REG[79h]) is based on the
display width and programmed using the following formula.
Main Window Line Address Offset bits 9:0
= display width in pixels
÷
(32
÷

= 320 pixels
