Description
This bit controls the DMA buffer mode:
Field in which the layer gets actually enabled once the
LayerN_Enable bit is set. This bit is used to invert the internal odd/
even signal. If the result of the operation Layer_Start_Field xor OE
is true the layer is enabled, otherwise the layer stays disabled until
the OE signal changes.
In non-interlaced modes:
this bit must be set to 1’b1 since the internal odd/even signal is
forced to zero.
In interlaced modes:
LayerNStartY (0x10,E230) >= 0, set this bit to 0
LayerNStartY (0x10,E230) < 0, set this bit to 1
If this bit is set, the incoming pixels are premultiplied with alpha.
That disables the new x alpha multiplication in the mixer stage if
alpha blending is enabled.
Controls which alpha value is used for blending in the layer mixer
stage
Chroma upsample filter operation mode
Chroma upsample filter enable
This bit indicates if the register upload into the shadow area is still in
progress.
This register reads always 0 if the screen timing generator is not
enabled
Alpha value for LUT programming
Red value for LUT programming
Green value for LUT programming
1 = Always toggle between buffer A and B (A=odd field, B=even
field).
0 = No buffer toggle, always fetch from buffer spec A.
1 = Use previous alpha
0 = Use alpha of current layer
1 = use this mode if input samples are arranged interspersed
0 = use this mode if input samples are arranged co-sited
1 = chroma upsample filter is enabled
0 = chroma upsample filter is in bypass mode
1 = New register upload possible, previous upload is complete
0 = Upload in progress, DO NOT reprogram any registers as the
results are undetermined
0 = Disable layer N
1 = Enable layer N
