Write/Erase of Flash memory

This section describes the procedure to issue a command to start the automatic
algorithm and how to perform the operations of the read/reset, write, chip erase, sector
erase, sector erase suspend, and sector erase restart.
Write/Erase of Flash Memory
The flash memory can execute the automatic algorithm by performing the read/reset, write, chip erase,
sector erase, sector erase suspend, and sector erase restart operations to write in cycle into the bus of the
command sequence (See Table 25.4-1). The write cycle into each bus needs to be performed consecutively.
Besides, the automatic algorithm can detect the end time with data polling function or other functions.
After normal termination, it returns to the read/reset state.
In the following section, the following items regarding the write/erase on the flash memory are described.
• Read/reset state
• Writing Data
• All data erasing (chip all erase)
• Any data erasing (sector erase)
• Suspend Sector erasing
• Restart Sector erasing
