DI/DO
Host clock input. Only used in Type2.
Chip select input pin, active low.
Address input pins.
Data bus D15 pin, D[15:8] is the high byte of the data bus, D15
also used as A0 when 8-bit Host data size.
In 8-bit mode, internal register high byte (D15:8) will accessed
at data bus [7:0] when A0 = 1, low byte (D7:0) will accessed at
data bus [7:0] when A0 = 0.
