N25Q128 - 1.8 V
Instructions
All attempts to access the memory array during a Write Status Register cycle, a Write Non
Volatile Configuration Register, a Program cycle or an Erase cycle are ignored, and the
internal Write Status Register cycle, Write Non Volatile Configuration Register, Program
cycle or Erase cycle continues unaffected, the only exception is the Program/Erase
Suspend instruction (PES), that can be used to pause all the program and the erase cycles
but the Program OTP (POT), Bulk Erase (BE) and Write Non Volatile Configuration Register.
The suspended program or erase cycle can be resumed by mean of the Program/Erase
Resume instruction (PER). During the program/erase cycles also the polling instructions (to
check if the internal modify cycle is finished by mean of the WIP bit of the Status Register or
of the Program/Erase controller bit of the Flag Status register) are also accepted to allow the
application checking the end of the internal modify cycles, of course these polling
instructions don't affect the internal cycles performing.
