NOTES:  
1. The first six address pins for each port serve dual functions. When MBSEL = VIH, the pins serve as memory address inputs. When MBSEL = VIL, the pins serve as mailbox  
address inputs.  
2. Each bank has an input pin assigned that allows the user to toggle the assignment of that bank between the two ports. Refer to Truth Table I for more details.
