1. Do not apply BEF# = VIL, BES1# = VIL and BES2 = VIH at the same time
2. X can be VIL or VIH, but no other value.
3. OE# = OEF# and OES#
WE# = WEF# and WES# for LS package only
4. Software mode only
5. With A19-A18 = VIL;SST Manufacturer’s ID = BFH, is read with A0=0,
SST34HF16x2C/D/S Device ID = 734AH, is read with A0=1
