Note
Window SwivelView Mode Select bits [1:0]
These bits select the SwivelView™ orientation that will be applied to the window. Each
window on the active display can have independent rotation, as the rotation is performed
prior to writing to the display buffer.
Window Data Type
This bit is used in conjunction with the Double Buffer Enable bit (REG[36h] bit 6) and
determines whether the data being input from the host will be double-buffered. This bit
must be set before the window data is written, as the window coordinates will be latched
internally to be used by the display pipe during display cycles.
When this bit = 0, the data being written from the Host is intended for single buffer only.
When this bit = 1, the data being written from the Host is intended for double buffer oper-
ation.
While double buffering is enabled, the window coordinates should not be modified.
If the Input Data Format is YUV 4:2:0 (REG[2Ah] bits 3-0 = 1001b), the Window Data
Type bit must not be changed while the YYC is busy (REG[58h] bit 4 = 1b).
