Block Erase Command
This command erases the data in the specified block. Execute the block erase command as explained
here following.
(1) Transfer the “2016” command code with the 1st byte.
(2) Transfer addresses A8 to A15 and A16 to A23 with the 2nd and 3rd bytes respectively.
(3) Transfer the verify command code “D016” with the 4th byte. With the verify command code, the
erase operation will start for the specified block in the flash memory. Write the highest address of
the specified block for addresses A8 to A23.
After block erase ends, the result of the block erase operation can be known by reading the status
register. For more information, see the section on the status register.
Each block can be erase-protected with the lock bit. For more information, see the section on the data
protection function.
