Erasing All Data from Flash Memory (Chip Erase)

This section describes the procedure for issuing the chip erase command and erasing
all the data from flash memory.
Erasing All Data from Flash Memory (Chip Erase)
To erase all the data from the flash memory, you can erase by sending the chip erase command in the
command sequence table (See Table 25.4-1) to the target sector in the flash memory.
Chip deletion command is done by six bus operations. When data writing into the target address ends at the
sixth cycle, the chip erase operation is started. Before chip erasing, the user need not perform programming
to flash memory. While the automatic algorithm is executed, the flash memory writes "0" to check
conditions before erasing all the cells automatically.
