9.7 Port 8

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 9.7. The register setting of the timer W has priority for functions of the pins P84/FTIOD,

P83/FTIOC, P82/FTIOB, and P81/FTIOA. 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.
