Description
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
Blue value for LUT programming
Address register for LUT programming, no auto-increment is
supported.
This enables read/write access by the host:
LUT enable signal
The bits 31:24 in 32 bpp mode are ANDed with this mask (input for
KEY2).
Not available when PF_10B_MODE(see 0x10 E2BC)is on.
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
1 = Host access enabled.
0 = Host access disabled.
0 = bypass LUT
1 = Allow data to flow through LUT
