STATUS REGISTER
The software status register provides status on whether the flash
memory array is available for any Read or Write operation,
whether the device is Write enabled, and the state of the memory
Write protection. During an internal Erase or Program operation,
the status register may be read only to determine the completion
of an operation in progress. Table 2 describes the function of
each bit in the software status register.

Note:
1. Only BP0, BP1, BP2 and BPL are writable.
2. All register bits are volatility
3. All area are protected at power-on (BP2=BP1=BP0=1)
