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.

2)This Parameter is valid at toggle bit timing in asynchronous read only. (timing diagram 6.21 and 6.22)

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.
