Each SRD bit
Data Protect Function (Block Lock)
Each block in Figure 1.149 has a nonvolatile lock bit to specify that the block is protected (locked) against erase/write.
The lock bit program command is used to set the lock bit to 0 (locked). The lock bit of each block can be read out using
the read lock bit status command.
Whether block lock is enabled or disabled is determined by the status of the lock bit and the lock bit disable bit in flash
memory control register 0.
(1) When the lock bit disable bit = "0", a specified block can be locked or unlocked by the lock bit status (lock bit data).
If lock bit data = "0" (locked), they are disabled against erase/write. On the other hand, if lock bit data = "1" (unlocked) they
are enabled for erase/write.
(2) When the lock bit disable bit = "1", all blocks are unlocked regardless of the lock bit data, and enabled for erase/write.
In this case, the lock bit data is set to "1" (unlocked) after erasure, so that the lock bit is disabled.
The status register indicates the flash memory operating status and whether an erase or program operation has
terminated normally or in error. Table 1.69 details the status register. The contents of this register can be read out only
by writing the read status register command (70
status register. After a reset, the status register is set to "80
After power-on, the write state machine (WSM) status is set to "1".
The write state machine (WSM) status indicates the operating status of the RY/BY pin output. This status bit is set to "0"
during an auto write or auto erase operation and is set to "1" when the operation is completed.
