Hello,According to the description of freerun mode1: The CP core free runs when the TMDS clock is not detected on the selected HDMI port

or it the video resolution of HDMI stream processed by the part does not match the video resolution programmed in PRIM_MODE[3:0] and


That means,freerun mode1 doesn't focus on the vertical frequency. But if I set V_FREQ[2:0] to 50Hz, The CP core will start freerun when the input frequency is 60Hz.

How can I make the CP core accept both 50Hz and 60Hz, so it won't start freerun when the vertical frequency change?

Thanks a lot.
