All pins must have the same level.
Intel Bus Mode or Motorola Bus Mode
By connecting this pin to either
the bus interface can be adapted to either
Intel or Motorola environment. The data is
interpreted either in Intel or Motorola
manner; i.e. little or big endian convention.
I/M = low: Intel bus mode
I/M = high: Motorola bus mode
Address Bit 31
