P84/
ExIRQ12
/SCK0/ExTMI0
The pin function is switched as shown below according to the combination of the C/
A
bit in
SMR of SCI_0, the CKE1 and CKE0 bits in SCR, and the P84DDR bit.
When the ISS12 bit in ISSR16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ12
input pin. When the TMI0S bit in PTCNT0 is set to 1, this pin can be used as the
TMI0 (TMI0/TMRI0) input pin. To use this pin as the
ExIRQ12
input pin, clear the P84DDR
bit to 0.
When this pin is used as the P84 output pin, the output format is NMOS push-pull output.

/SDA1
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_1 and the P83DDR bit.
When the ISS11 bit in ISSR16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ11
input pin. To use this pin as the
ExIRQ11
input pin, clear the P83DDR bit to 0.
When this pin is used as the P83 output pin, the output format is NMOS push-pull output. The
output format for SDA1 is NMOS open-drain output, and direct bus drive is possible.

The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_1 and the P82DDR bit.
When the ISS10 bit in ISSR16 of the interrupt controller is set to 1, this pin can be used as the
ExIRQ10
input pin. To use this pin as the
ExIRQ10
input pin, clear the P82DDR bit to 0.
When this pin is used as the P82 output pin, the output format is NMOS push-pull output. The
output format for SCL1 is NMOS open-drain output, and direct bus drive is possible.
