9.4
A Suspend Sector Erase instruction executed during an Erase timeout period, in addition to
suspending the Erase cycle, terminates the time out period.
The Toggle flag bit (DQ6) stops toggling when the PSD 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 bit (DQ6) stops toggling between 0.1µs and 15µs after the Suspend
Sector Erase instruction has been executed. The PSD is then automatically set to READ
mode.
If an Suspend Sector Erase instruction was executed, the following rules apply:
●
●
●
●
Resume Sector Erase
If a Suspend Sector 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-FS7 or CSBOOT0-CSBOOT3) is
high. (See
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 cannot be programmed, and only responds to Resume Sector
Erase and Reset 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.
