1. Address format A14-A0 (Hex),
Addresses A19-A15 can be VIL or VIH, but no other value, for the Command sequence.
2. WA = Program Byte address
3. SAX for Sector-Erase; uses AMS-A12 address lines
BAX for Block-Erase; uses AMS-A16 address lines
AMS = Most significant address
AMS = A19 for SST39VF088
4. The device does not remain in Software Product ID mode if powered down.
5. With AMS-A1 = 0; SST Manufacturerâs ID = BFH, is read with A0 = 0
SST39VF088 Device ID = D8H, is read with A0 = 1
6. Both Software ID Exit operations are equivalent
