Other Parts Discussed in Thread: TVP5158
I want to use the interrupt of TVP5158.
I have set:
0xAD= 0|(1<<6) |(1<<7);
0xF4h is set to enable all interrupt.
But there is no interrupt is generated.( ps : I connect the INTREQ pin of TVP5158 with a GPIO pin of DSP).
I want to know:
1 "signal prsent detect interrupt" is generated one time for each frame,or onlly when the TVP5158 is power on.
2 What "weak signal" means? Does it mean there are some video lines is lost ?
3 When will "Video (HV) lock change interrupt" be generated. Does it mean there are some video channel is wrong?
4 What does "Macrovision change interrupt" mean?
Could you help me?
