9-bit Bus: D[17:9]
8-bit Bus: D[17:10]
While using serial interface, the unused pins must be connected to VSS.
Reserved Pin (Supporting Pin)
- The supporting pins can reduce the influences from stresses on the function pins.
These pins must be connected to external ground as the ESD protection circuit.
