*1:Outputs 01h at protected sector group addresses and outputs 00h at unprotected sector group addresses.
*2:When VID is applied, both Bank 1 and Bank 2 become Autoselect mode, which leads to the simultaneous operation
unable to be executed. Consequently, specifying the bank address is not demanded. However, the bank address
needs to be indicated when Autoselect mode is read out at command mode; because then it becomes OK to
activate simultaneous operation.
*3: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.
