6/29

CMD

Command pin is a bidirectional line. The host and card drivers are operating in push-pull

configuration.

DAT0-3

All data lines are bi-directional lines. Host and card drivers operate in push-pull mode.

CLK

Clock is a host to card signal. CLK operates in push-pull mode.

Feedback (return) clock is a feedback clock signal from level shifter to the host for controlling

delays.

CD

IN1, IN2

Selection pins. When IN1 and IN2 are set to disabled state, all the data bus will be in high-

impedance. When enabled, all the data bus will be working as a level translator between

port A and port Bn (refer to the truth table for possible pin configuration).
