Standby power levels are not be realized until the block-erase operation has finished.
Also, asserting RP# aborts the block-erase operation, and array contents at the
addressed location are indeterminate. The addressed block should be erased before
programming within the block is attempted.

Suspend and Resume
An erase or programming operation can be suspended to perform other operations, and
then subsequently resumed. Table 24 shows the Suspend and Resume command bus-
cycles.
Note:
All erase and programming operations require the addressed block to remain unlocked
with a valid voltage applied to VPEN throughout the suspend operation. Otherwise, the
block-erase or programming operation will abort, setting the appropriate Status
Register error bit(s). Also, asserting RP# aborts suspended block-erase and
programming operations, rendering array contents at the addressed location(s)
indeterminate.

To suspend an on-going erase or program operation, issue the Suspend command to
any device address. The program or erase operation suspends at pre-determined points
during the operation after a delay of tSUSP. Suspend is achieved whenSTS (in RY/BY#
mode) goes high, SR[7,6] = 1 (erase-suspend) or SR[7,2] = 1 (program-suspend).
Note:
Issuing the Suspend command does not change the read mode of the device. The
device will be in Read Status Register mode from when the erase or program command
was first issued, unless the read mode was changed prior to issuing the Suspend
command.
Not all commands are allowed when the device is suspended. Table 25 shows which
device commands are allowed during Program Suspend or Erase Suspend.
