*1 : A-1 is for Byte mode. At Byte mode, DQ8 to DQ14 are High-Z and DQ15 is A-1, the lowest address.
*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 enables
to activate simultaneous operation.
