Example VPP Supply Connections
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
