When a programming operation is executing, issuing the Program Suspend command requests the
WSM to suspend the programming algorithm at predetermined points. The device continues to
output Status Register data after the Program Suspend command is issued. Programming is
suspended when Status Register bits SR[7,2] are set. Suspend latency is specified in
“Program and Erase Characteristics” on page
To read data from the device, the Read Array command must be issued. Read Array, Read Status
Register, Read Device Identifier, CFI Query, and Program Resume are valid commands during a
program suspend.
During a program suspend, deasserting CE# places the device in standby, reducing active current.

suspend. If RST# is asserted, the device is reset.
Program Resume
The Resume command instructs the device to continue programming, and automatically clears
Status Register bits SR[7,2]. This command can be written to any address. If error bits are set, the
Status Register should be cleared before issuing the next instruction. RST# must remain deasserted
