Note 1: For details about the port level switching function, see Section 8.4, "Port Input Level Switching Function."
Notes: P223 is an input mode-only port.
• The circle denotes a pin.
• The symbol denotes a parasitic diode. Make sure the voltage applied to each pin does not exceed the VCCE voltage.
• The input capacitance of each pin is approximately 10 pF.
