Table 47. Command Interface States - Modify Table, Next Output

Note: 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 com-

mand 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 Con-

troller.

3. At Power-Up, all banks are in Read Array mode. Issuing a Read Array command to a busy bank, results in undetermined data out-

put.

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.
