CLKN_POL

Polarity inverse control on output CLKNO signal just before CLKNO pin.

not inversed. (default)

Polarity inverse. good for 27MHz/54MHz clock output.

CLKP_POL

Polarity inverse control on output CLKPO signal just before CLKPO pin.

not inversed. good for 27MHz/54MHz clock output.(default)

Polarity inverse.

IRQENA

Enable/Disable the interrupt request through the IRQ pin.

Disable (default)

Enable

IRQPOL

Select the polarity of interrupt request through the IRQ pin.

Falling edge requests the interrupt and keeps its state until cleared

(default)

Rising edge requests the interrupt and keeps its state until cleared

ADET_MODE

Define the polarity of state register and interrupt request for audio detection.

No interrupt request by the audio detection

Make the interrupt request rising only when the audio signal comes in

Make the interrupt request falling only when the audio signal goes out

Make the interrupt request rising and falling when the audio comes in

and goes out (default)

VDET_MODE

Define the polarity of state register and interrupt request for video detection.

No interrupt request by the video detection

Make the interrupt request rising only when the video signal comes in

Make the interrupt request falling only when the video signal goes out

Make the interrupt request rising and falling when the video comes in

and goes out (default)
