the Flash memory sector(s). Before and during
Erase time-out, any instruction other than Sus-
pend Sector Erase and Resume Sector Erase in-
structions abort the cycle that is currently in
progress, and reset the device to Read mode.
During a Sector Erase, the memory status maybe
checked by reading the Error Flag (DQ5) bit, the
Toggle Flag (DQ6) bit, and the Data Polling Flag
(DQ7) bit, as detailed in the section entitled “Pro-
gramming Flash Memory”, on page 100.
During execution of the Erase cycle, the Flash
memory accepts only Reset and Suspend Sector
Erase instructions. Erasure of one Flash memory
sector may be suspended, in order to read data
from another Flash memory sector, and then re-
sumed.
Suspend Sector Erase.
When a Sector Erase
cycle is in progress, the Suspend Sector Erase in-
struction canbe used to suspend the cycle by writ-
ing 0B0h to any address when an appropriate
Sector Select(FS0-FS7 or CSBOOT0-CSBOOT3)
is High. (See Table 83). This allows reading of
data from another Flash memory sector after the
Erase cycle has been suspended. Suspend Sec-
tor Erase is accepted only during an Erase cycle
and defaults to Read mode. A Suspend Sector
Erase instruction executed during an Erase time-
out period, in addition to suspending the Erase cy-
cle, terminates the time out period.
The Toggle Flag (DQ6) bit stops toggling when the
internal logic is suspended. The status of this bit
must be monitored at an address within the Flash
memory sector being erased. The Toggle Flag
(DQ6) bit stops toggling between0.1

after the Suspend Sector Erase instruction has
been executed. The Flash memory is then auto-
matically set to Read mode.
If an Suspend Sector Erase instruction was exe-
cuted, the following rules apply:
– Attempting to read from a Flash memory sector
that was being erased outputs invalid data.
– Reading from a Flash sector that was not being
erased is valid.
– The Flash memory cannotbe programmed, and
only responds toResume Sector Erase and Re-
set Flash instructions (Read is an operation and
is allowed).
– If a Reset Flash instruction is received, data in
the Flash memory sector that was being erased
is invalid.
Resume Sector Erase.
If
Erase instruction was previously executed, the
erase cycle may be resumed with this instruction.
The Resume Sector Erase instruction consists of
writing 030h to any address while an appropriate
Sector Select (FS0-FS7or CSBOOT0-CSBOOT3)
is High. (See Table 83.)
