Description
initial (before scaling) Layer N width, in pixels.
Pedestal to be added to Upper input
(pedestal_up is a 2’s complement number from -128 to 127)
The pedestal removal is performed after the color key unit, before
dithering.
Pedestal to be added to Middle input
(pedestal_mid is a 2’s complement number from -128 to 127)
The pedestal removal is performed after the color key unit, before
dithering
Pedestal to be added to Lower input
(pedestal_low is a 2’s complement number from -128 to 127)
The pedestal removal is performed after the color key unit, before
dithering

Input format indicator
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.
0 = data expansion from 8 to 9 bit through multiply by two (zero in
LSB)
1 = data expansion from 8 to 9 bit through multiply by two (MSB
in LSB position)
2,3 = data expansion from 8 to 9 bit through multiply by two
(undither operation)
0 = Input is in 4:4:4 format
1 = Input is in 4:2:2 format
1 = Always toggle between buffer A and B (A=odd field, B=even
field).
0 = No buffer toggle, always fetch from buffer spec A.
