Table 44. Command Interface States - Lock Table, Next Output State

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's output state.

2. CI = Command Interface, CR = Configuration Register, BEFP = Buffer Enhanced Factory Program, P/E. C. = Program/Erase Con-

troller, WA0 = Address in a block different from first BEFP address.

3. If the P/E.C. is active, both cycles are ignored.

4. BEFP Exit when Block Address is different from first Block Address and data are FFFFh.

5. Illegal commands are those not defined in the command set.
