26.6.3 Erasing All Data in the Flash Memory (Chip Erase)

This section describes the procedure for issuing the chip erase command to erase all
data in the flash memory.
I Erasing all data in the flash memory (chip erase)
To erase all data in the flash memory, repeatedly send the chip erase command in the
command sequence table (see Table 26.4-1 "Command sequence table") to the relevant sector
in the flash memory.
The chip erase command is executed in six bus operations. When the write operation is
completed in the 6th cycle, the chip erase operation will start. During the chip erase operation,
the user does not need to write to the flash memory before erasing; during execution of the
automatic erase algorithm, "0" will automatically be written to all cells of the flash memory for
verification before erasure.
