Program/Erase Resume (D0h)

The Program/Erase Resume command allows a suspended program or erase operation to be resumed and

continue programming a Flash page or erasing a Flash memory block where it left off. The Program/Erase Resume

command is accepted by the device only if the SUS bit in the Status/Control equals 1 and the RDY/BSY bit equals

0. If the SUS bit equals 0 or the RDY/BSY bit equals 1, the device ignores the Program/Erase Resume command.

As with the Program/Erase Suspend command, the Write Enable command does not need to be issued prior to the

Program/Erase Resume command being issued. Therefore, the Program/Erase Resume command operates

independently of the state of the WEL bit in the Status/Control register.

To perform Program/Erase Resume command, the CS pin must first be asserted and the D0h command must be

clocked into the device.

No address bytes need to be clocked into the device, and any data clocked in after the command is ignored. When

the CS pin is deasserted, the program or erase operation currently suspended resumes within a time of t

RES. The

SUS bit in the Status/Control register is then reset back to the logic “0” state to indicate the program or erase

operation is no longer suspended. In addition, the RDY/BSY bit in the Status/Control register indicates that the

device is busy performing a program or erase operation. The complete command must be clocked into the device

before the CS pin is deasserted, and the CS pin must be deasserted on a byte boundary (multiples of eight bits).

Otherwise, no resume operation is performed.

During a simultaneous erase suspend/program suspend condition, issuing the Program/Erase Resume command

results in the program operation resuming first. After the program operation has been completed, the

Program/Erase Resume command must be issued again in order for the erase operation to be resumed.

While the device is busy resuming a program or erase operation, any attempts at issuing the Program/Erase

Suspend command is ignored. Therefore, if a resumed program or erase operation needs to be subsequently
