Description
Display Not Active.
0: Display active.
1: Display not active (i.e., blanking or border).
Vertical Not Active.
0: Vertical display active.
1: Vertical display not active (i.e., vertical blanking or border).
Vertical Sync Active.
0: Vertical sync not active.
1: Vertical sync active.
Reserved.
Flip.
0: Newly programmed DC_FB_ST_OFFSET (DC Memory Offset 010h[27:0]) has not
1: Previously programmed DC_FB_ST_OFFSET (DC Memory Offset 010h[27:0]) has
DC Line Count. This value is the current scan line of the DC Engine. The DC Engine,
which fetches the frame buffer data, performs compression and de-compression, and
overlays cursor data, typically runs several scan lines ahead of the actual display. This
allows for buffering and scaling/filtering of graphics data.
Video Flip.
0: Newly programmed DC_VID_Y_ST_OFFSET (DC Memory Offset 020h[27:0]) has not
1: Previously programmed DC_VID_Y_ST_OFFSET (DC Memory Offset 020h[27:0]) has
Signature Complete. A 1 in this bit indicates that the CRC signature operation has com-
pleted and the resulting signature value may be safely read by software.
Even Field Indicator. When interlacing is enabled, a 1 in this bit indicates that the cur-
rent field is the even field.
Reserved.
Dot Line Count. This value is the current scan line of the display. This field is NOT syn-
chronized in hardware, so software should read this value twice to ensure that the result
is correct.
