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

Not all commands are allowed when the device is suspended.
device commands are allowed during Program Suspend or Erase Suspend.
During Suspend, array-read operations are not allowed in blocks being erased or
programmed.
A block-erase under program-suspend is not allowed. However, word-program under
erase-suspend is allowed, and can be suspended. This results in a simultaneous erase-
suspend/ program-suspend condition, indicated by SR[7,6,2] = 1.
