NOTE:
1. If OE is disabled at the same time or before CE is disabled, the output will go to high-z by tOEZ.
If CE is disabled at the same time or before OE is disabled, the output will go to high-z by tCEZ.
If CE and OE are disabled at the same time, the output will go to high-z by tOEZ.
These parameters are not 100% tested.

Note:
1. These parameters are tested based on INT bit of interrupt register. Because the time on INT pin is related to the pull-up and pull-down resistor value.
2. The device may reset if tRP < tRP min(200ns), but this is not guaranteed.
