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 device.
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, and
6. Setting the recovery phase parameter (T5) will adjust the duration between successive accesses on the
7. One cycle is the period of the Expansion Bus clock.
8. Clock to output delay for all signals will be a maximum of 15 ns for devices requiring operation in
