Background Mode (See Table 4)
0 = The Local Background Control bit (see DMM[5] and DMDI[7]) sets the state of each character
background.
1 = Sets all displayed background pixels to gray. The gray level is specified by bits VM1[6:4]
below. This bit overrides the local background control bit.
Note: In internal sync mode, the background mode bit is set to 1.
Background Mode Brightness (% of OSD White Level)
000 = 0%
001 = 7%
010 = 14%
011 = 21%
100 = 28%
101 = 35%
110 = 42%
111 = 49%
Blinking Time (BT)
00 = 2 fields (33ms in NTSC mode, 40ms in PAL mode)
01 = 4 fields (67ms in NTSC mode, 80ms in PAL mode)
10 = 6 fields (100ms in NTSC mode, 120ms in PAL mode)
11 = 8 fields (133ms in NTSC mode, 160ms in PAL mode)
Blinking Duty Cycle (On : Off)
00 = BT : BT
01 = BT : (2 x BT)
10 = BT : (3 x BT)
11 = (3 x BT) : BT

Horizontal Position Offset
(OSD video is not inserted into the horizontal blanking interval)
00 0000 = Farthest left (-32 pixels)
10 0000 = No horizontal offset
11 1111 = Farthest right (+31 pixels)
