Block Erase Command
This command erases the data in the specified block. Execute the block erase command as explained
here following.
When block erasing ends, the RTS1 (BUSY) signal changes from the “H” to the “L” level. 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.
