10.2.21 Erase Suspend (75h)
The Erase Suspend instruction “75h”, allows the system to interrupt a sector or block erase operation
and then read from or program data to, any other sector or block. The Write Status Register instruction
(01h) and Erase instructions (20h, 52h, D8h, C7h, 60h ) 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 time of “tsus” (See AC
Characteristics) is required to suspend the erase operation. The BUSY bit in the Status register will
clear to 0 after Erase Suspend. A power-off during the suspend period will reset the device and release
the suspend state.

10.2.22 Erase Resume (7Ah)
The Erase Resume instruction must be written to resume the sector or block erase operation after an
Erase Suspend. After issued the BUSY bit in the status register will be set to a 1 and the sector or block
will complete the erase operation. Resume instructions will be ignored unless an Erase Suspend
operation is active.
