Program/Erase Suspend
The Program/Erase Suspend instruction allows the controller to interrupt a Program or an
Erase instruction, in particular: Sector Erase, Subsector Erase, Page Program, Dual Input
Page Program, Dual Input Extended Page program, Quad Input Page Program and Quad
Input Extended Page program can be suspended and erased.
Note:
Bulk Erase, Write Non Volatile Configuration register and Program OTP cannot be
suspended.
After a Program/Erase Suspend instruction the bit 2 of the Flag Status register is
immediately set to 1 and, after a latency time, both the WIP bit of the Status Register and
the Program/Erase controller bit (Not WIP) of the Flag Status Register are cleared (to 0 and
to 1 respectively).
The Suspended state is reset if a power-off is performed or after resume.
After a sector erase instruction has been suspended, another erase instruction is not
allowed; however, it is possible to perform program and reading instructions on all the
sectors except the one whose erase cycle is suspended. Any read instruction issued on this
sector outputs Don't Care data.
After a subsector erase instruction has been suspended, neither an erase instruction or a
program instruction is allowed; only a read instruction is allowed on all sectors except the
one containing the subsector whose erase cycle is suspended. Any read instruction issued
on this sector outputs Don't Care data.
After a program instruction has been suspended, neither a program instruction or an erase
instructions is allowed; however, it is possible to perform a read instruction on all pages
except the one whose program cycle is suspended. Any read instruction issued on this page
outputs Don't Care data.
It's possible to nest a suspend instruction inside another suspended one just once, meaning
that it's possible for example to send to the device an erase instruction, then suspend it,
then send a program instruction and in the end suspend it as well. In this case the next
Program/Erase Resume Instruction resumes the more recent suspended modify cycles,
another Program/Erase Resume Instruction is need to resume also the former one.
