01h*2
*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 to A9, both Bank 1 and Bank 2 are put into Autoselect mode, which makes simultaneous
operation unable to be executed. Consequently, specifying the bank address is not required. However, the bank
address needs to be indicated when Autoselect mode is read out at command mode, because then it becomes
possible 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) 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 (at BYTE mode, (BA) 1Ch) , as well as at (BA) 0Fh (at BYTE mode, (BA) 1Eh) .
