*1:Sector Group can be protected by “Sector Group Protection”, “Extended Sector Group Protection” and
“New Sector Protection (PPB Protection)”.
Outputs 01h at protected sector group addresses and outputs 00h at unprotected sector group addresses.
*2:A read cycle at address (BA) 01h outputs device code. When 227Eh is output, it indicates that two additional
codes, called Extended Device Codes, will be required. Therefore the system may continue reading out these
Extended Device Codes at the address of (BA) 0Eh, as well as at (BA) 0Fh
