• P86/ExIRQ14/SCK2/ExTMIX
The pin function is switched as shown below according to the combination of the C/A bit in
SMR of SCI_2, the CKE1 and CKE0 bits in SCR, and the P86DDR bit.
When the ISS14 bit in ISSR16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ14 input pin. When the TMIXS bit in PTCNT0 is set to 1, this pin can be used as the
TMIX (TMCIX/TMRIX) input pin. To use this pin as the ExIRQ14 input pin, clear the
P86DDR bit to 0.
When this pin is used as the P86 output pin, the output format is NMOS push-pull output.

• P85/ExIRQ13/SCK1/ExTMI1
The pin function is switched as shown below according to the combination of the C/A bit in
SMR of SCI_1, the CKE1 and CKE0 bits in SCR, and the P85DDR bit.
When the ISS13 bit in ISSR16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ13 input pin. When the TMI1S bit in PTCNT0 is set to 1, this pin can be used as the
TMI1 (TMI1/TMRI1) input pin. To use this pin as the ExIRQ13 input pin, clear the P85DDR
bit to 0.
When this pin is used as the P85 output pin, the output format is NMOS push-pull output.
