Bit Description

0x0C

Default Value Y

DEF_VAL_EN; default value

enable

Freerun mode dependent

on DEF_VAL_AUTO_EN

Forces freerun mode on

DEF_VAL_AUTO_EN; default

value automatic enable

Disables freerun mode

When lock is lost,

freerun mode can

be enabled to

output stable

timing, clock, and a

set color

Enables automatic freerun

mode

DEF_Y[5:0]; default value is Y;

this register holds the Y default

value

Y[7:0] = {DEF_Y[5:0], 0, 0}

Default Y value

output in freerun

mode

0x0D

Default

Value C

DEF_C[7:0]; default value is C;

the Cr and Cb default values

are defined in this register

Cr[3:0] = {DEF_C[7:4]},

Cb[3:0] = {DEF_C[3:0]}

Default Cb/Cr value

output in freerun

mode; default

values give blue

screen output

0x0E
