Name
REG11: Sets the sampling point when down-sampling Y signal.
LPFYPASS: Sets whether the Y signal passes or bypasses the LPF circuit.
LPI0ON2~LPI0ON0: Sets whether the Cb signal passes or bypasses the LPF circuit.
LPQ0ON2~LPQ0ON0: Sets whether the Cr signal passes or bypasses the LPF circuit.
Bit
LPQ0ON1
LPI0ON1
0 (default): Samples Y0, Y2 and Y4.
1: Samples Y1, Y3 and Y5.
0 (default): The Y signal passes through the LPF circuit. System delay (9 clocks) is added by the
1: The Y signal bypasses the LPF circuit which adds a 1-clock delay.
