Note：(The default clk period is 20ns)
1. The IO16 is valid when the SD bus width is 16-bit or
32-bit and system address is DATA port (i.e. CMD
is high) and the value of INDEX 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
and system address is DATA port (i.e. CMD is high)
and the value of INDEX port is memory data
Register index (ex. F0H, F2H, F6H or F8H)
