Our customer have a question about i.MX6 GPIO DC parameter.
Please see of Table 22 in IMX6DQCEC.
We understand i.MX6DQ recognizes input signal as High certainly when it is over VIH (0.7 * OVDD) in general.
In addition, i.MX6DQ rarely recognizes input signal as High when it is between VIL (0.3 * VDD) and VIH.
Next, please see footnote 4, it says "Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled".
According to these description, our customer guessed that the minimum voltage which is recognized as High is VIL + hysteresis (250mV).
Is this correct?
Or there is a possibility that i.MX6DQ recognizes the input voltage as High if it exceeds VIL only little?
