Table 41. Command Interface States - Modify Table, Next Output
Note: 1. CI = Command Interface, CR = Configuration Register, EFP = Enhanced Factory Program, Quad EFP = Quadruple Enhanced Fac-
tory Program, DWP = Double Word Program, QWP = Quadruple Word Program, P/E. C. = Program/Erase Controller.
2. At Power-Up, all banks are in Read Array mode. A Read Array command issued to a busy bank, results in undetermined data out-
put.
3. The two cycle command should be issued to the same bank address.
4. If the P/E.C. is active, both cycles are ignored.
5. The Clear Status Register command clears the Status Register error bits except when the P/E.C. is busy or suspended.
6. 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 Query mode, depending on the
command issued. Each bank remains in its last output state until a new command is issued. The next state does not depend on the
bank’s output state.
