This is composed by the Block Address (BA) and either A
SST Factory Unique Id is read at Address Range: 000000H to 000007H (128-bit). This segment is always locked by SST.
User ID is read at Address range: 000080H to 0000FFH (128-words).
Lock Status of User Segment is read with A
SST Manufacturer ID = 00BFH, is read with A1 = 0 and A0 = 0
SST34WA32x3 Device ID = 975BH, is read with A1 = 0 and A0 = 1
SST34WA32x4 Device ID = 975AH, is read with A1 = 0 and A0 = 1
the “A0H” command is issued in order to enable the Eight Words Program Command.
