1. Address format A14-A0 (Hex), Addresses A15-A19 can be VIL or VIH, but no other value, for Command sequence for SST39LF/VF160
2. DQ15 - DQ8 can be VIL or VIH, but no other value, for Command sequence
3. WA = Program word address
4. SAX for Sector-Erase; uses A19-A11 address lines
BAX, for Block-Erase; uses A19-A15 address lines
5. The device does not remain in Software Product ID Mode if powered down.
6. With A19-A1 =0; SST Manufacturer’s ID= 00BFH, is read with A0 = 0,
SST39LF160/SST39VF160 Device ID = 2782H, is read with A0 = 1
7. Both Software ID Exit operations are equivalent
