Section 9 I/O Ports
9.5
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 pins P84/FTIOD,
P83/FTIOC, P82/FTIOB, and P81/FTIOA. P80/FTCI 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.
9.5.1
PCR8 selects inputs/outputs in bit units for pins to be used as general I/O ports of port 8.

Description
When each of the port 8 pins P87 to P80 functions as an
general I/O port, setting a PCR8 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
