Table 43. Command Interface States - Lock Table, Next State

Note: 1. 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.

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

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

4. BEFP is allowed only when Status Register bit SR0 is set to ‘0’. BEFP is busy if Block Address is first BEFP Address. Any other

commands are treated as data.

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

6. if N=0 go to Buffer Program Confirm. Else (N

≠ 0) go to Buffer Program Load 2 (data load).

7. if N=0 go to Buffer Program Confirm in Erase Suspend. Else (N

≠ 0) go to Buffer Program Load 2 in Erase Suspend.
