Function

PLLLOCKIT_EN

PLLLOCK Pad IT Enable

0: The PLLLOCK pad use is determined by the DDECCONT7 register

1: The PLLLOCK pad is used as the IT pad (in this case, register DDECCONT7 is irrelevant)

RGBADJUST_EN

RGB Gain Adjustment Enable

0: RGB Gain Adjustment mechanism is disabled (Default)

1: RGB Gain Adjustment enabled

RGBADJUST[5:0]

RGB Gain Adjustment Value

This adjusts the RGB channel with the CVBS channel. The adjustment gain is expressed as [1 +

RGBADJUST]. It is applied on Y, Cr and Cb when in RGB mode. It is applied on Cr and Cb in YCrCb

mode. RGBADJUST is coded in 2's complement (+31 to -32).

011111: Maximum positive value of approx. +0.25

000000: RGBADJUST = 0 (Default)

100000: Maximum negative value of approx. -0.25

PLLLOCK_MASK

Mask for interruption on change of PLLLOCK status

VLOCK_MASK

Mask for interruption on change of VLOCK status

HLOCK_MASK

Mask for interruption on change of HLOCK status

TVSTDID_MASK

Mask for interruption on change of TVSTDID status

0: Interrupt is not masked

1: Interrupt is masked

FBDEL[3:0]

delays the FB signal wrt the RGB flow

The delay is coded in 2's complement (from -16 to 15) The Default value is 0, expressed in 4 x fSC clock

periods.
