Status register
The status register contains a number of status and control bits that can be read or set (as
appropriate) by using specific instructions. See
a 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 and to
meet the needs of modularized applications, the M25PE16 features the following flexible
data protection mechanisms:
Protocol-related protections
Power on reset and an internal timer (t
changes while the power supply is outside the operating specification.
Program, erase and write 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 Reset (Reset) signal can be driven Low to freeze and reset the internal logic. For
the specific cases of program and write cycles, the designer should refer to

pulse.
In addition to the low power consumption feature, the deep power-down mode offers
extra software protection from inadvertent write, program and erase instructions while
the device is not in active use.
