Hi community.

 

Our customer use  Vybrid5R (SVF522R3K1CMK4) analog video input (VADCSE0) to terminal

enter  the NTSC video signal to display an image on the TFT.

 

The detection of input signal use the registers of  "havesignal" of Bit 0 , describe on  Vybrid_Reference_Manual _-_ R_Series_ (Auto) _-_ Rev_6.pdf

  of sect 61.6.22 Video Mode (VDEC_VIDMOD).

 

Would you please tell me the conditions to become havesignal is "0" when it becomes to video signal is fail.

Max input voltage and minimum input voltage.

 

Or Example) When input signal is ** V more voltage is applied, fail register rises

The voltage input of up to ** V ~ ** V, the screen disturbed ,but  does not rise fail to register.
