11
PF_U2C
R/W
0
Controls upper channel format within layer
0 = data untouched
1 = data conversion two’s compliment <-> binary offset
The conversion takes place after the color key unit before the
undither unit.
10
PF_M2C
R/W
0
Controls middle channel format within layer
0 = data untouched
1 = data conversion two’s compliment <-> binary offset
The conversion takes place after the color key unit before the
undither unit.
9
PF_L2C
R/W
0
Controls lower channel format within layer
0 = data untouched
1 = data conversion two’s compliment <-> binary offset
The conversion takes place after the color key unit before the
undither unit

PF_OFFSET2
R/W
0
Denes pixel offset (in bytes) within a multi-pixel 64-bit word for
channel 2 for semi-planar and planar modes.
0, 2 or 4 for 10-bit YUV 4:2:2 semi-planar format
0 to 7 for 8-bit YUV 4:2:2 semi-planar format
The number will be truncated to the closest even number for
channel 2
2:0
PF_OFFSET1
R/W
0
Denes pixel offset (in bytes) within a multi-pixel 64-bit word.
0, 2 or 4 for 10-bit YUV 4:2:2 semi-planar format
0 or 4 for 10-bit (20 bpp) packed YUV 4:2:2 format
0, 2, 4 or 6 for 8-bit (16 bpp) packed YUV 4:2:2 or 16-bit varible
format
0 or 4 for 32-bit varible format
0 to 7 for all the other formats
Offset 0x10 E2BC

PF_ENDIAN
R/W
0
Input format endian mode
0: Same as system endian mode
1: Opposite of system endian mode
Not available when PF_10B_MODE is on.

PF_PIX_MODE
R/W
0
Pixel key output modes
00: Both keys ‘0’
01: Bits [1:0] of V/B output
10: Key 2 Bit [7] of alpha output
11: Key 2 AND of pixel key and alpha is not zero
Mode 11 is not available when PF_10B_MODE is on.
