Port 8 is a general I/O port also functioning as a timer W I/O pin. Each pin of the port 8 is shown
in figure 9.5. The register setting of the timer W has priority for functions of the P84/FTIOD,
P83/FTIOC, P82/FTIOB, and P81/FTIOA pins. The P80/FTCI pin also functions as a timer W
input port that is connected to the timer W regardless of the register setting of port 8.
Port 8 has the following registers.
