Command interface state tables
Table 47.
1. CI = Command Interface, CR = Configuration register, BEFP = Buffer Enhanced Factory program, P/E C = Program/Erase
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. 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
