• Block Erase Command (20
By writing the command code “20
the confirmation command code “D0
the second bus cycle that follows, the block erase (erase and
erase verify) operation starts for the block address of the flash
memory to be specified.
Whether the block erase operation is completed can be confirmed
by read status register or the RY/BY status flag of flash memory
control register. To read the status register, write the status
register command “70
“0” at the same time the block erase operation starts and returned
to “1” upon completion of the block erase operation. The read
status mode at this time remains active until the read array
command (“FF
The RY/BY status flag register is set to “0” during block erase
operation and “1” when the block erase operation is completed as
is the status register bit 7 (SR7).
After the block erase ends, erase results can be checked by
reading the status register. For details, refer to the section where
the status register is detailed.
