NOTES:
1. The first six address pins for each port serve dual functions. When
MBSEL
= V
IH
, the pins serve as memory address inputs. When
MBSEL
= V
IL
, 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.
