23.4 Register
Bit 0:
The RDY/BSY output is provided to identify the status of auto operation. This bit is a functional bit
for monitoring this function by communicating with the CPU. If flash memory is in auto operation,
"0" is output to show that flash memory is busy. As flash memory completes auto operation and
goes into a ready state, "1" is output and the next command will be accepted. If the result of auto
operation is faulty, this bit continues to output "0." It returns to "1" upon a hardware reset.
Bit [7:4]: Protect bit (x: A combination setting can be made for each block)
The protect bit (4-bit) value corresponds to the protect status of each block. If this bit is "1," the
corresponding block is in a protected state. A protected block cannot be overwritten.

Before issuing a command, make sure that flash memory is in a ready state.
If a command is issued when flash memory is busy, a right command cannot
be generated and there is the possibility that subsequent commands may not
be able to be input. In this case, you must return to a normal functional state
by executing a system reset or issuing a reset command.
