Note 1: For details about the port level switching function, see Section 8.4, "Port Input Level Switching Function."
Notes: • During processor and external extension modes, P41-P43 are external bus interface control signal pins, but their
functional description in this block diagram is omitted.
• The circle denotes a pin.
• The symbol
• The input capacitance of each pin is approximately 10 pF.
