qBlock 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 sec-
ond bus cycle that follows, the block erase (erase and erase verify)
operation starts for the block address of the flash memory to be speci-
fied.
Whether the block erase operation is completed can be confirmed
by read status register or the RY/BY status flag of flash memory con-
trol register. At the same time the block erase operation starts, the
read status register mode is automatically entered, so that the con-
tents 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.
