1.
CI = Command Interface, CR = Configuration Register, EFP = Enhanced Factory Program, Quad EFP = Quadruple
Enhanced Factory Program, DWP = Double Word Program, QWP = Quadruple Word Program, P/E. C. = program/erase
Controller, IS = Illegal State, ES = Erase suspend, PS = Program suspend.
2.
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.
3.
At Power-Up, all banks are in Read Array mode. A Read Array command issued 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/EC is active, both cycles are ignored.
6.
The Clear Status Register command clears the status register error bits except when the P/EC is busy or suspended.
