Pin Function
P65DDR
Pin Function
The pin function is switched as shown below according to the OS3 to OS0 bits in TCSR of
TMR_1 and TMR_X and the P67DDR bit. When the IRQ3E bit in IER of the interrupt
controller is set to 1, this pin can be used as the IRQ3 input pin.
The pin function is switched as shown below according to the combination of the OEB bit in
TOCR of FRT and the P66DDR bit. When the CCLR1 and CCLR0 bits in TCR of TMR_1 are
both set to 1, this pin can be used as the TMRI1 input pin.
The pin function 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 external
clock is selected with the CKS2 to CKS0 bits in TCR of TMR_1, this pin can be used as the
TMCI1 input pin.
