NOTES:
1. EX_ALE is not valid in simplex mode of operation.
2. Setting the address phase parameter (T1) will adjust the duration that the address appears to the external
3. Setting the data setup phase parameter (T2) will adjust the duration that the data appears prior to a data
4. Setting the data strobe phase parameter (T3) will adjust the duration that the data strobe appears (read or
5. Setting the data hold strobe phase parameter (T4) will adjust the duration that the chip selects, address,
6. Setting the recovery phase parameter (T5) will adjust the duration between successive accesses on the
7. T is the period of the clock measured in ns.
