Type: I: Input pin, O: Output pin, B: Bidirectional pin, P: Power supply pin, NC: No connection pin
Note: 1. NC (no connection) pins must be left open.
2. Pin names (signal names) that begin with a Z have negative (inverted) logic.
3. VSS0 is the logic system ground and VSS1 is the IDE interface driver ground.
