Section 8 I/O Ports
• P66/IRQ6/KIN6/FTOB
The function of port 6 pins is switched as shown below according to the combination of the
OEB bit in TOCR of FRT and the P66DDR bit.
When the KMIMR6 bit in KMIMR of the interrupt controller is cleared to 0, this pin can be
used as the KIN6 input pin. When the EIVS bit in SYSCR is cleared to 0 and the IRQ6E bit in
IER of the interrupt controller is set to 1, this pin can be used as the IRQ6 interrupt input pin.

• P65/KIN5/FTID
The function of port 6 pins is switched as shown below according to the P65DDR bit.
When the ICIDE bit in TIER of FRT is set to 1, this pin can be used as the FTID input pin.
When the KMIMR5 bit in KMIMR of the interrupt controller is cleared to 0, this pin can be
used as the KIN5 input pin.

Pin function
• P64/KIN4/FTIC
The function of port 6 pins is switched as shown below according to the P64DDR bit.
When the ICICE bit in TIER of FRT is set to 1, this pin can be used as the FTIC input pin.
When the KMIMR4 bit in KMIMR of the interrupt controller is cleared to 0, this pin can be
used as the KIN4 input pin.
