18.6.9 Parallel Dual Display

MB86R02 'Jade-D' incorporates two independent display controllers that operate in parallel.

controller 0

controller 1

If only using one output, se the display enable flag in DCM0/1 register to zero for the unsed display

controller. The two display controllers work independently, therefore different resolutions can be used

by each controller and therefore each works asynchronously to the other.

The phase difference indicated above of each frame should be taken into consideration when drawing

figures synchronously on two screens.

This assumes that the controllers have the same timing parameters and share the same clock source

such as the internal PLL.

If the 'display enable' flags of the controllers are activated sequentially, then the phase difference of

VSYNC will remain very small and stays constant.

Dual Display functionality is not possible with RSDS panels.
