and GND pins are separated into four groups to provide individual power supply
connections for the address bus buffers, data bus buffers, and all other output buffers and
internal logic. It is recommended that all pins be connected to power and ground as
indicated. NC pins are reserved by Motorola for future use and should have no external
connection.
