Program / Erase Suspend
The Program/Erase Suspend instruction allows the system to
interrupt a Sector or Block Erase and page or Quad page
program operation and then read from, any other sector or block.
The Write Status Register instruction and Program instruction
and Sector/Block Erase instructions are not allowed during
suspend. Program/Erase Suspend is valid only during the
Program and Sector or Block Erase operation. If written during
the Chip Erase, the Program/Erase Suspend instruction is
ignored. A maximum of TSUS is required to suspend the program /
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.
