6.1.76 CLOCK POLARITY REGISTER– OFFSET FBH(Default=0FH)
BIT
FUNCTION
TYPE
DESCRIPTION
[1:0]
VDET_MODE
RW
Define the polarity of state register and interrupt request for
video detection.
0: No interrupt request by the video detection
1: Make the interrupt request rising only when the video
comes in
2: Make the interrupt request falling only when the video goes
out
3: Make the interrupt request rising and falling whenthe video
comes in and goes out
[3:2]
ADET_MODE
RW
Define the polarity of state register and interrupt request for
audio detection.
0: No interrupt request by the audio detection
1: Make the interrupt request rising only when the audio
comes in
2: Make the interrupt request falling only when the audio goes
out
3: Make the interrupt request rising and falling whenthe audio
comes in and goes out
[4]
IRQPOL
RW
Select the polarity of interrupt request through theIRQ pin.
0: Falling edge requests the interrupt and keeps itsstate until
cleared
1: Rising edge requests the interrupt and keeps itsstate until
cleared
[5]
IRQENA R/W
RW
Enable/Disable the interrupt request through the IRQ pin
0: Disable
1: Enable
[6]
PIXCLK_P_POL
RW
0:The polarity of PIXCLK_Pis not inversed
