Notes:
1. CI = Command Interface: CR = Configuration register: BEFP = Buffer Enhanced Factory program: P/E C = Program/Erase controller: IS =
Illegal State: BP = Buffer program: ES = Erase suspend: WA0 = Address in a block different from first BEFP address.
2. If the P/E C is active, both cycle are ignored.
3. BEFP Exit when Block Address is different from first Block Address and data are FFFFh.
4. Illegal commands are those not defined in the command set.
5. –: not available. In this case the state remains unchanged.
6. If N = 0 go to Buffer Program Confirm. Else (not = 0) go to Buffer Program Load 2 (data load)
7. If N = 0 go to Buffer Program Confirm in Erase suspend. Else (not = 0) go to Buffer Program Load 2 in Erase suspend.
8. 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.
9. Buffer Program will fail at this point if any block address is different from the first address
