Protection modes
The environments where non-volatile memory devices are used can be very noisy. No SPI
device can operate correctly in the presence of excessive noise. To help combat this, the
M25P64 features the following data protection mechanisms:

Program, Erase and Write Status Register instructions are checked that they consist of
a number of clock pulses that is a multiple of eight, before they are accepted for
execution.
All instructions that modify data must be preceded by a Write Enable (WREN)
instruction to set the Write Enable Latch (WEL) bit. This bit is returned to its reset state
by the following events:

The Block Protect (BP2, BP1, BP0) bits allow part of the memory to be configured as
read-only. This is the Software Protected Mode (SPM).
