We have problem with the SSPD auto detection for CP input in separaeted sync (RGB&HV).
Once a while the SSPD auto detection reports the CUR_SYNC_SRC[1:0] = 0x03, which is wrong (detect composite sync instead separated sync). The failure rate is very low, about 1/100 or less, so it is difficult to replicate the error
I guess it's the matter how and when the VGA cable is plug in, and the ADV7441A may see a glitch on the Green signal !???
Btw, my software follows the flowchart as described on page 159-Figure 49 in the Hardware Manual rev J., with SSPD statemachine runs continously
