To read data from the device, the Read Array command must be issued. Read Array,

Read Status Register, Read Device Identifier, Read CFI, 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.

8.5

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 33, “Program Suspend/

Resume Flowchart” on page 74).

8.6

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.
