Command interface state tables
Table 46.
1. The output state shows the type of data that appears at the outputs if the bank address is the same as the command
2. CI = Command Interface, CR = Configuration Register, BEFP = Buffer Enhanced Factory Program, P/E. C. =
3. At Power-up, all banks are in Read Array mode. Issuing a Read Array command to a busy bank, results in undetermined
4. The two cycle command should be issued to the same bank address.
5. If the P/E.C. is active, both cycles are ignored.
