BIT

FUNCTION

R/W

DESCRIPTION

RESET

HPLC

R/W

Reserved for internal use.

EVCNT

R/W

1 = Even field counter in special mode.

0 = Normal operation

PALC

R/W

Reserved for future use.

SDET

R/W

ID detection sensitivity. A '1' is recommended.

TBC_EN

0 = TBC off.

BYPASS

R/W

It controls the standard detection and should be set to ‘1’ in normal use.

SYOUT

R/W

1 = Hsync output is disabled when video loss is detected

0 = Hsync output is always enabled

Reserved

0 = Disabled.

PKILL

R/W

1 = Enable automatic noisy color killer function in PAL mode.

0 = Disabled.

SKILL

R/W

1 = Enable automatic noisy color killer function in SECAM mode.

0 = Disabled.

CBAL

R/W

0 = Normal output

1 = special output mode.

FCS

R/W

1 = Force decoder output value determined by CCS.

0 = Disabled.

LCS

R/W

1 = Enable pre-determined output value indicated by CCS when video loss

is detected.

0 = Disabled.

CCS

R/W

When FCS is set high or video loss condition is detected when LCS is set

high, one of two colors display can be selected.

1 = Blue color.

0 = Black.

BST

R/W

1 = Enable blue stretch.

0 = Disabled.
