Be initialized to "0" when resetting.
This bit can be read and written.
[bit 4]:RDY
This bit indicates the operation status of the auto algorithm (write/erase).
While this bit is "0", writing or erasing is carried out by the auto algorithm, and new write or erase
commands cannot be received. Data cannot be read from the flash memory address. The read data
indicates the flash memory status.
Refer to "21.5 Auto Algorithm Execute State" for details.
This bit is not initialized at reset. (It conforms the status of flash memory at that time.)
Read is only possible. Writing does not affect the value of this bit.
[bit 3 to 1]:(reserved bit)
There are reserved bit. The read value is irregular, and write operation does not affect.
[bit 0]:(reserved bit)
It is reserved bit. These bits indicate "0" when read. Always write "0" to this bit. Writing "1" does not
guarantee.
Be initialized to "0" when resetting.
Always write "0". These bits indicate "0" when read.
0 Disables writing to the flash memory and enables 32-bit reading [Initial
value]
1 Enables writing to the flash memory and disables 32-bit reading
(programming mode)
0 During writing/erasing, commands that read, write, and erase data
cannot be received.
1 Commands that read, write, and erase data can be received.
