Datasheet
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.
V
PP
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 V
PP
= V
IL
, absolute hardware write protection is provided for all device blocks. If V
PP
is at
or below V
PPLK
, programming operations halt and SR[3] is set indicating a V
PP
-level error. Block
lock registers are not affected by the voltage level on V
PP
; they may still be programmed and read,
even if V
PP
is less than V
PPLK
.
