23.6.5
Temporarily Stopping the Sector Deletion
This section explains the procedure of issuing the sector deletion temporary stop
command and temporarily stopping the deletion of a sector from the flash memory.
This command can read the data from the sector not being deleted.
■
Temporarily Stopping the Sector Deletion
The sector deletion from the flash memory can be temporarily stopped by sending the sector deletion
temporary stop command, listed in the command sequence table (see "23.4 Method of Starting the
Automatic Algorithm in Flash Memory"), to the target sector in the flash memory.
The sector deletion temporary stop command stops the sector deletion operation temporarily, and enables
the data reading from the sector not being deleted. In this case, only the read operation can be executed,
but the write operation cannot be done. This command is valid only during the sector deletion operation
including the deletion waiting time, but it is ignored during the chip deletion operation or the write
operation.
This command is executed by writing the deletion temporary stop code (B0
H
). In this case, the address
must indicate an address within the flash memory. During the deletion temporary stop operation, the
reissued deletion temporary stop command is ignored.
If the sector deletion temporary stop command is input during the sector deletion waiting period, the sector
deletion wait is immediately terminated to stop the deletion operation, and the flash memory enters the
deletion stop status. If the sector deletion temporary stop command is input during the sector deletion
operation after the sector deletion waiting period, the flash memory enters the deletion temporary stop
status after a lapse of up to 20
µ
s. The sector deletion temporary stop command must be executed 20
µ
s or
more after the sector deletion command or sector deletion restart command is issued.
