Table 11-17. DCU_MODE field descriptions (continued)
Field
Description
ADDB
Two-bit value to be added to pixel blue component for dithering
ADDG
Two-bit value to be added to pixel green component for dithering
ADDR
Two-bit value to be added to pixel red component for dithering
DDR_MODE
Enables Special DDR Mode (see Section 11.4.9, Special DDR mode). Select BLEND_ITER =
4 when enabled.
BLEND_ITER
Defines the number of planes used for blending.
3’d4:Four plane blending
3’d3:Three plane blending
3’d2:Two plane blending
default: Two plane blending
PDI_SYNC_LOCK Defines the number of frames which should be received by the PDI validation state machine
before it locks and sets the PDI_LOCK_DET bit in the PDI Status Register (see
Section 11.3.4.26, PDI Status Register)
PDI_INTERPOL_E Control Bit to decide whether the conversion from YCbCr 4:2:2 to 4:4:4 needs to be done using
N
interpolation or Chroma value is same for two pixels
1’b1:Interpolation is enabled.
1’b0:Chroma value is same for two pixels
RASTER_EN
Enables raster scanning of pixel data including the VSYNC and HSYNC signals and the pixel
data. Changes to this bit take effect after the completion of the current frame.
1’b1: Enabled
1’b0:Disabled
PDI_EN
Enables the PDI
1’b1: Enabled
1’b0:Disabled
PDI_BYTE_REV Controls the byte ordering in Narrow Mode
1’b0:LSB is followed by MSB data
1’b1:MSB is followed by LSB data
PDI_DE_MODE Enables the PDI data Enable Mode. Here Data Enable is treated as an input.
1’b0: Value on data Enable signal is ignored
1’b1: Data enable signal must be present in incoming stream
PDI_NARROW_M Enables the PDI Narrow Mode (refer to Section 11.8.1.5, Normal and Narrow Mode)
ODE
1’b0: Narrow Mode is Disabled
1’b1: Narrow Mode is Enabled
PDI_MODE
Defines the different modes in which PDI is operating
2’b00: 8 bit monochrome data input
2’b01: 16 bit RGB 565 format
2’b10:18 bit RGB 666 data format.
2’b11:YCbCr data in 4:2:2 format.
PDI_SLAVE_
MODE
Enables PDI slave Mode
1’b0:Disabled
1’b1:Enabled
