Note 2: denotes a pin.
Note 3:
denotes a parasitic diode. Make sure the voltage applied to each port will not exceed VCCE.
Note 1: Although P00-P07, P10-P17, P20-P27, P30-P37, and P41-P47 serve as external bus interface
control signal pins during external extended and processor modes, their functional description in this
block diagram is omitted.
