Pin Function
The pin function is switched as shown below according to the combination of the OEA bit in
TOCR of FRT, the OS3 to OS0 bits in TCSR of TMR_Y, and the P61DDR bit.
The pin function 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 CCLR1 and CCLR0 bits in TCR of TMR_X are both set to 1, this pin can be used as
the TMIX (TMRIX) input pin. When the external clock is selected with the CKS2 to CKS0
bits in TCR of TMR_0, this pin can be used as the TMCI0 input pin.
