PP
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.
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
Resume Flowchart” on page
Program Protection
When VPP = V
VPP is at or below V
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 V
