Function
This is a general-purpose I/O port.
This is a data input pin of I/O simple serial interface 2.
Because this input is used as required when is performing input
operations, and it is I/O simple serial interface 2 necessarey to stop
outputs by other functions unless such outputs are made
intentionally.
This is a general-purpose I/O port.
This function becomes valid when data output from I/O simple
serial interface 2 is disabled.
This is a data output pin of I/O simple serial interface 2.
This function becomes valid when data output from I/O simple
serial interface 2 is enabled.
This is a general-purpose I/O port.
This function becomes valid when clock output from I/O simple
serial interface 2 is disabled.
This is clock output pin of I/O simple serial interface 2.
This function becomes valid when clock output from I/O simple
serial interface 2 is enabled.
This is an I/O pin for the lower 8-bit of the external data bus.
This is power supply to the digital circuit.
This is a ground level of the digital circuit.
