method because other than the HiddenROM mode, it is the same as the sector group protect previously men-
tioned. Refer to “8. Secor Group Protection” in
protect setting.
Take note that other sector groups will be affected if an address other than those for the HiddenROM area is
selected for the sector group address, so please be careful. Pay close attention that once it is protected, protection
CANNOT BE CANCELLED.
Detailed in “Hardware Sequence Flags Table” are all the status flags that can determine the status of the bank
for the current mode operation. The read operation from the bank that does not operate Embedded Algorithm
returns a data of memory cell. These bits offer a method for determining whether a Embedded Algorithm is
completed properly. The information on DQ
sector is consecutively read, then the DQ
erasing sector is consecutively read. This allows the user to determine which sectors are erasing and which are
not.
The status flag is not output from bank (non-busy bank) not executing Embedded Algorithm. For example, there
is bank (busy bank) which is now executing Embedded Algorithm. When the read sequence is [1] <busy bank>,
[2] <non-busy bank>, [3] <busy bank>, the DQ
memory cell is outputted. In the erase-suspend read mode with the same read sequence, DQ
in the [1] and [3].
In the erase suspend read mode, DQ
outputted.
