Vertical blanking on/off
0 = Vertical blanking (VBLK) off (default)
1 = Vertical blanking (VBLK) on
Clock output enable
0 = SCLK output is high impedance (default)
1 = SCLK output is enabled
Note: To achieve lowest power consumption, outputs placed in the high-impedance state should not be
left floating. A 10-kΩ pulldown resistor is recommended if not driven externally.
Note: When enabling the outputs, ensure the clock output is not accidently disabled.

YCbCr OUTPUT NOTES
(TVPOE) (VDPOE)
0 X High impedance After both YCbCr output enable bits are programmed
X 0 High impedance After both YCbCr output enable bits are programmed
1 1 Active After both YCbCr output enable bits are programmed
(1) VDPOE default is 1, and TVPOE default is 0.
