• P61/FTOA/KIN1
The function of port 6 pins is switched as shown below according to the combination of the
OEA bit in TOCR of FRT, and the P61DDR bit.
When the KMIM1 bit in KMIMR6 of the interrupt controller is cleared to 0, this pin can be
used as the KIN1 input pin. To use this pin as the KIN1 input pin, clear the P61DDR bit to 0.

• P60/FTCI/KIN0
The function of port 6 pins is switched as shown below according to the P60DDR bit.
When the CKS1 and CKS0 bits in TCR of FRT are both set to 1, this pin can be used as the
FTCI input pin. When the KMIM0 bit in KMIMR6 of the interrupt controller is cleared to 0,
this pin can be used as the KIN0 input pin. To use this pin as the KIN0 input pin, clear the
P60DDR bit to 0.
