Notes:
1. The output state shows the type of data that appears at the outputs if the bank address is the same as the command address. A bank can
be placed in Read Array, Read Status Register, Read Electronic Signature or Read CFI mode, depending on the command issued. Each
bank remains in its last output state until a new command is issued to that bank. The next state does not depend on the bank output state.
2. CI = Command Interface: CR = Configuration Register: BEFP = Buffer Enhanced Factory Program: P/E. C. = Program/Erase Controller.
3. At Power-Up, all banks are in Read Array mode. Issuing a Read Array command to a busy bank, results in undetermined data output.
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.
