Deleting All Data Items From The Flash Memory (Chip Deletion) - Fujitsu F2MC-16LX Hardware Manual

23.7.3 Deleting all Data Items from the Flash Memory (Chip
Deletion)
This section describes the procedure for deleting all data items from the flash memory
issuing the chip deletion command.
■ Deleting the Data From the Flash Memory (Chip Deletion)
All data items can be deleted from the flash memory by continuously sending chip deletion
commands, listed in the command sequence table (see Table 23.5-1 in Section "23.5 Activating
the Automatic Algorithm of the Flash Memory"), to the target sector within the flash memory.
The chip deletion command is executed by six bus operations. The chip deletion starts when
the writing in the 6th cycle is completed. Before the chip deletion, the user need not perform
writing in the flash memory. During execution of the automatic deletion algorithm, the flash
memory performs verification by writing "0" before automatically deleting all cells.
