01h*¹
*1 : 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 was output, this indicates that there will
require two additional codes, called Extended Device Codes. Therefore the system may continue reading out
these Extended Device Codes at the address of (BA) 0Eh, as well as at (BA) 0Fh.
