R/W

[7]

0x0

0: normal

1: force image to background color

R/W

[6]

0x0

top & botton border control

0: pixel replicating

1: background color blending

R/W

[5]

0x0

left & right border control:

0: pixel replicating

1: background color blending

R/W

[4]

0x0

force output data as described in bit [1] when

the maximum output vertical is reached.

R/W

[3]

0x0

force output data as described in bit [1] when

an abnormal codition is detected by the sync

measurement module.

R/W

[2]

0x0

When the scaler is not running, force the

ouput data to black if this bit is 0 or to the

background color if the bit is 1.

R/W

[1]

0x0

If an abnormality is detected in the sync

measurement module or if the maximum

output vertical total has been reached, force

the ouput data to black if this bit is 0 or to

white if this bit is 1.

R/W

[0]

0x0

During blanking, force output data to black if

this bit is 0 or to the background color if this

bit is 1.

SCL_AVERAGE_IK

0x0AF0

[7:3]

Reserved

R/W

[2:1]

0x0

0x0: bypass

0x1: horizontal average by 2

0x2: horizontal average by 4

0x3: horizontal average by 8

R/W

[0]

0x0

0: no pixel average

1: enable pixel averager

This function is only necessary if the input

horizontal resolution is greater than 1280

pixels.
