This resister is used to monitor the status of the flash memory and to indicate the block protection
status.

normal command not only is sent when the command is issued to a busy inside
but also there is a possibility that the command after that cannot be input. In that
case, please return by system reset or the reset command.
Ready/Busy flag bit
The RDY/BSY output is provided as a means to monitor the status of automatic operation.
This bit is a function bit for the CPU to monitor the function. When the flash memory is in
automatic operation, it outputs "0" to indicate that it is busy. When the automatic operation
is terminated, it returns to the ready state and outputs "1" to accept the next command. If
the automatic operation has failed, this bit maintains the "0" output. By applying a
hardware reset, it returns to "1."
Each of the protection bits (4 bits) represents the protection status of the corresponding
block. When a bit is set to "1," it indicates that the block corresponding to the bit is
protected. When the block is protected, data cannot be written to it.
Protection area setting (for each 256 kB)
0000:No blocks are protected
xxx1:Block 0 is protected
xx1x:Block 1 is protected
x1xx:Block 2 is protected
1xxx:Block 3 is protected
