Notes: In order to perform a normal read of flash memory, SWE must be cleared to 0.
Also note that verify-reads can be performed during the programming/erasing process.

: Normal mode
: On-board programming mode
2. Do not make a state transition by setting or clearing multiple bits simultaneously.
3. After a transition from erase mode to the erase setup state, do not enter erase mode without passing
through the software programming enable state.
4. After a transition from program mode to the program setup state, do not enter program mode without
passing through the software programming enable state.
