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 Program/Erase Controller 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. N/A: 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.
