UCD90160: logic controlled GPO failed somehow

Hi Team,

is there any sequence or timing restriction for logic controlled GPO? or others limitation?

we found that the GPO may fail to turn active when all of input signals are satisfied, but the GPO status can be changed through change the output mode(active driver/open drain) or even change the delay time from 20ms to 0ms (the GPO status change at all of input signal are all stable DC)

Not all of the boards show the same thing, some of the boards may see this problem easily but others not.

here is the setting in GUI (the PCD_SLP_S3_R_N has been set to active low already)

here is the waveform with all input signals above

here is the waveform with failed GPO(CH1)

here is the waveform with expected GPO (we can get good GPO waveform somehow with AC power cycle)
