Block Erase Command (2016/D016)
By writing the command code “2016” in the first bus cycle and
the confirmation command code “D016” and the block address in
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. At the same time the block erase operation
starts, the read status register mode is automatically entered, so
that the contents of the status register can be read out. The status
register
bit 7 (SR7) is set to “0” at the same time the block erase
operation starts and is returned to “1” upon completion of the
block erase operation. In this case, the read status register mode
remains active until the read array command (FF16) is written.
The RY/BY status flag is “0” during block erase operation and
“1” when the block erase operation is completed as is the status
register bit 7.
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.
