Data Protection (Block Lock)
Each block in Figure 1.176 has a nonvolatile lock bit that indicates protection (block lock) against erasing/writing. A
block is locked (writing "0" for the lock bit) with the lock bit program command. Any lock bit can be read with the read lock
bit status command.
Block lock disable/enable is determined by the status of the lock bit and execution status of the lock bit disable and lock
bit enable commands.
(1) After reset and the lock bit enable command is executed, the specified block can be locked/unlocked using the lock
bit (lock bit data). Blocks with a "0" lock bit data are locked and cannot be erased or written to. Blocks with a "1" lock bit
data are unlocked and can be erased or written to.
(2) After the lock bit disable command has been executed, all blocks are unlocked regardless of the lock bit data status
and can be erased or written to. In this case, any lock bit data that was "0" before the block was erased is set to "1"
(unlocked) after erasing.
Status Register (SRD)
The status register indicates the flash memory operating status and whether an erase or program operation has
terminated normally or in error. It can be read by using the read status register command (70
