Flash Memory Write/Erase Operations - Fujitsu F2MC-16LX Hardware Manual

26.6 Flash Memory Write/Erase Operations

This section describes various operation procedures after issuing the automatic
algorithm start command, including flash memory read/reset, write, chip erase, sector
erase, sector erase suspend and sector erase resume.
I Flash memory write/erase
The flash memory performs a bus write cycle according to the command sequence (see Table
26.4-1 "Command sequence table") for operations such as read/reset, write, chip erase, sector
erase, sector erase suspend, and erase resume to execute the automatic algorithm. Write cycle
to each bus must be executed consecutively. The end of the automatic algorithm can be
detected with such functions as the data polling function. After a normal end, the operational
state returns to the read/reset state.
This section describes the following items related to flash memory write/erase operations.
• Setting the flash memory to read/reset state
• Writing data
• Erasing all data (entire chip erase)
• Erasing arbitrary data (sector erase)
• Suspending sector erase
• Resuming sector erase
