Port
The general-purpose ports output high or low floating signals to external circuits, and reads high or low level signals
Table 10-1 shows the relations between each port and port register.
The general-purpose ports are classified into I/O ports, input ports, and output ports.
The I/O port is the bit I/O ports, which can be set in the input or output mode in 1-bit (1-pin) units.
