The program or erase operation suspends at pre-determined points during the
operation after a delay of t
suspend) or SR[7,2] = 1 (program-suspend).
Throughout the Block Erase Suspend or Program Suspend period, the addressed block
must remain unlocked and a valid voltage applied to VPP. Otherwise, the erase or
program operation will abort, setting the appropriate Status Register error bit(s). Also,
WP# must remain unchanged.
Asserting RST# aborts suspended block-erase and programming operations -- array
contents at the addressed locations are indeterminate. The addressed block should be
erased, and the data re-programmed.
Not all commands are allowed when the device is suspended.
device commands are allowed during Program Suspend or Erase Suspend.
During Suspend, reading from a block that is being erased or programmed is not
allowed. Also, programming to a block that is in erase-suspend state is not allowed,
and if attempted, will result in Status Register program error to be set (SR4 = 1).
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.
To resume a suspended program or erase operation, issue the Resume command to
any device address. The read mode of the resumed partition is unchanged; issue the
Read Status Register command to return the partition to Read Status mode. The
operation continues where it left off, and the respective Status Register suspend bits
are cleared.
