i.MX6Q ONOFF debounce not 750ms

The IMX6DQRM states that PMIC_ON_REQ will be asserted if the ONOFF input is held low for a debounce duration of 750ms. On our custom board I am seeing a debounce time of only 76 micro seconds. 76us is not a reasonable duration for mechanical debouce, it should be at least 20ms. I've attached a scope trace showing ONOFF and PMIC_ON_REQ.


1) Which clock is used to measure the ONOFF debounce time?

2) Is this an error in the RM or is it an indication of clock problem in our design?
