Writing to and Erasing Flash Memory

This section explains how to issue a command to start the automatic algorithm for a
read/reset, write, chip erase, sector erase, temporary sector erase stop, or sector erase
restart operation in flash memory.
■ Overview of Flash Memory Write/Erase
The automatic algorithm can be executed for the following operations in flash memory by executing bus
write cycles for the corresponding command sequence:
• Read/reset
• Write
• Chip erase
• Sector erase
• Temporary stop of sector erase
• Sector erase restart
The write cycles for each bus must always be executed continuously.
In addition, termination of the automatic algorithm can be checked using the data polling function. Flash
memory is set again to read/reset status after the automatic algorithm terminates normally.
