Erase Suspend
The Erase Suspend instruction allows the system to interrupt a
Sector or Block Erase operation and then read from any other
sector or block. The Write Status Register instruction and Sector /
Block Erase instructions are not allowed during suspend. Erase
Suspend is valid only during the Sector or Block Erase operation.
If written during the Chip Erase or Program operation, the Erase
Suspend instruction is ignored. A maximum of TSUS is required to
suspend the erase operation. The BUSY bit in the Software
Status Register will clear to “0” after Erase Suspend. A power-off
during the suspend period will reset the device and release the
suspend status.

Erase Resume
The Erase Resume instruction must be written to resume the
Sector or Block Erase operation after Erase Suspend. After
issued the BUSY bit in the Software Status Register will be set to
“1” and the sector or block will complete the erase operation.
Erase Resume instruction will be ignored unless an Erase
Suspend operation is active.
