9.5 Port 6
Port 6 is a general I/O port also functioning as a timer Z I/O pin. Each pin of the port 6 is shown in
figure 9.5. The register setting of the timer Z has priority for functions of the pins for both uses.

Figure 9.5 Port 6 Pin Configuration
Port 6 has the following registers.
• Port control register 6 (PCR6)
• Port data register 6 (PDR6)
9.5.1 Port Control Register 6 (PCR6)
PCR6 selects inputs/outputs in bit units for pins to be used as general I/O ports of port 6.

When each of the port 6 pins P67 to P60 functions as a
general I/O port, setting a PCR6 bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
