The factory default value for the software configuration register is 0x0102. This value is a combination of the following: binary bit 8 = 0x0100 and binary bits 00 through 03 = 0x0002.
Caution To avoid confusion, note that valid software configuration register values may be combinations of settings. For example, the factory default value 0x0102 for the software configuration register is actually a composite of settings in this register.
