Status Register
The Status Register contains a number of status and control bits that can be read or set (as
appropriate) by specific instructions. See
detailed description of the Status Register bits.
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
M25P16 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)
The Write Protect (W) signal allows the Block Protect (BP2, BP1, BP0) bits and Status
Register Write Disable (SRWD) bit to be protected. This is the hardware protected
mode (HPM)
In addition to the low power consumption feature, the Deep Power-down mode offers
extra software protection, as all Write, Program and Erase instructions are ignored.
