ADP bit
The Address Power-up (ADP) bit is a non-volatile writable bit that determines the initial address mode when the device
is powered on or reset. This bit is only used during the power on or device reset initialization period. When ADP=0(factory
default), the device will power up into 3-Byte address mode, the Extended Address Register must be used to access memory
regions beyond 128Mb. When ADP=1, the device will power up into 4-Byte address mode directly.
