Table 12-17. DCU_MODE field descriptions (continued)
Field
Description
18
PDI_EN
Enables the PDI
1’b1: Enabled
1’b0:Disabled
19
Controls the byte ordering in Narrow Mode
PDI_BYTE_REV 1’b0:LSB is followed by MSB data
1’b1:MSB is followed by LSB data
20
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
21
Enables the PDI Narrow Mode (refer to Section 12.8.2.4, Normal and Narrow Mode”)
PDI_NARROW_M 1’b0: Narrow Mode is Disabled
ODE
1’b1: Narrow Mode is Enabled
22–23
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.
24
Enables PDI slave Mode
PDI_SLAVE_MOD 1’b0:Disabled
E
1’b1:Enabled
25
TAG_EN
Enables the calculation of CRC only on the safety layers
1’b0: CRC calculated over the whole area of interest (area of interest given by SIG_DESC
registers)
1’b1: calculates CRC only on safety enabled layers
26
SIG_EN
Enables the signature calculator block
1’b0: signature calculator is disabled
1’b1: signature calculator is enabled
27
PDI_SYNC
Decides whether the PDI uses external or internal synchronization.
1’b0: External Synchronization. The PDI receives the SYNC (hsync,vsync) signals from
external source.
1’b1: Internal Synchronization. PDI extracts the SYNC information from the digital data.
29
EN_GAMMA
Enables/Disables the Gamma Correction
1’b0: Gamma correction is disabled
1’b1: Gamma Correction is enabled
30–31
DCU_MODE
DCU operating mode and pixel clock enable
2’b00: DCU off
2’b01: Normal mode. Pixel clock active and panel content controlled by layer configuration
2’b10: Test mode. Panel content fetched from CLUT/Tile memory
2’b11: Color Bar Generation. Pixel clock active and panel content controlled by color bar
registers.
12.3.4.13 BGND Register
Figure 12-16 represents the BGND register.
