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 Section 7.5,

“Program and Erase Characteristics” on page 45.

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.

VPP must remain at its programming level, and WP# must remain unchanged while in program

suspend. If RST# is asserted, the device is reset.

11.5

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

(see Figure 41, “Program Suspend/Resume Flowchart” on page 86).

11.6

Program Protection

When VPP = VIL, absolute hardware write protection is provided for all device blocks. If VPP is at

or below VPPLK, programming operations halt and SR[3] is set indicating a VPP-level error. Block

lock registers are not affected by the voltage level on VPP; they may still be programmed and read,

even if VPP is less than VPPLK.
