5.5 AC Characteristics for Asynchronous Read
See Timing Diagrams 6.3 and 6.4.
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 6.20 and 6.21)
5.6 AC Characteristics for Warm Reset (RP), Hot Reset and NAND Flash Core Reset
See Timing Diagrams 6.16, 6.17 and 6.18.
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.
