15
FPC
Simultaneous Flat Panel (or VOP) and CRT. Primary display is flat panel. Setting this 
bit activates the CRT DAC interface to allow simultaneous display of both panel and 
CRT. Leaving this bit reset forces the CRT DAC signals to zero.
This bit is ignored if bits [5:3] of this register are set to 0 or 4.
14
IUV
Interchange UV. Interchange byte order of the U and V bytes (see bits [7:6]). This 
applies only to DRGB mode (see bits [5:3]).
13:8
DIV
Clock Divider. GLIU clock divider to produce 14.3 MHz reference clock. Result must be 
equal to or less than 14.3 MHz. GLIU clock speed/DIV = reference clock.
7:6
FMTBO
Format Byte Order. The lower 24 bits of the DRGB output bus byte order can be modi-
fied for any required interface. These bits, along with bit 14, are used to output the follow-
ing combinations of byte order. This applies only to DRGB mode.

FMT
VP Output Format Select. Video Processor module display outputs formatted for CRT 
or flat panel. Resets to CRT; software must change if a different mode is required.
000: CRT.
001: Flat Panel.
010: Reserved.
011: Reserved.
100: CRT Debug mode.
101: Reserved.
110: VOP.
111: DRGB.
2:0
PID
VP Priority Domain. Video Processor module assigned priority domain identifier.
