*1 : A-1 is for Byte mode.
*2 : Outputs 01h at protected sector group addresses and outputs 00h at unprotected sector group addresses.
*3 : 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.
*4 : At WORD mode, a read cycle at address (BA) 01h (at BYTE mode, (BA) 02h) outputs device code. When 227Eh
(at BYTE mode, 7Eh) 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 (at BYTE mode, (BA) 1Ch) , as well as at (BA) 0Fh (at BYTE mode, (BA) 1Eh) .
