1. Address format A14-A0 (Hex), Addresses AMS-A15 can be VIL or VIH, but no other value, for the Command sequence.
AMS = Most significant address
AMS = A16 for SST39SF010A, A17 for SST39SF020A, and A18 for SST39SF040
2. BA = Program Byte address
3. SAX for Sector-Erase; uses AMS-A12 address lines
4. The device does not remain in Software Product ID mode if powered down.
5. With AMS-A1 = 0; SST Manufacturer’s ID = BFH, is read with A0 = 0,
SST39SF010A Device ID = B5H, is read with A0 = 1
SST39SF020A Device ID = B6H, is read with A0 = 1
SST39SF040 Device ID = B7H, is read with A0 = 1
6. Both Software ID Exit operations are equivalent
