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 LSE package only
4. Software mode only
5. With A19-A18 = VIL;SST Manufacturer’s ID = BFH, is read with A0=0,
SST34HF16x1C Device ID = 734BH, is read with A0=1
