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
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 reading the status register or the RY/BY Status Flag of flash
memory control register.
____
The RY/BY Status Flag is “0” during block erase operation and “1”
when the block erase operation is completed as is the status reg-
ister bit 7.
In case of using erase suspend function in the EW0 mode, check
that the erase sequence is shifted to erase suspend mode with
erase suspend flag. Reading the erase status flag after block
erase, the result of the block erase is gotten.
Do not execute this command for rewrite control program address
in the EW1 mode.
In the EW0 mode, 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.
