Note
1. The IO16 is valid when the SD bus width is 16-bit or
32-bit, and the system address is data port (i.e.
CMD is high) and the value of address port is
memory data register index.
ex. F0H, F2H, F6H or
F8H
2. The IO32 is valid when the SD bus width is 32-bit,
the system address is data port (i.e. CMD is high)
and the value of address port is memory data
register index
ex. F0H, F2H, F6H or F8H
