of SCI1, and the P34DDR bit.

Pin function

Note: * Output type is NMOS push-pull. When P34ODR = 1, it becomes NMOS

Switches as follows according to combinations of ICCR1 ICE bit of IIC1, SCR TE bit

of SCI1 and the P33DDR bit.

Pin function

Note: * When P33ODR = 1, it becomes NMOS open drain output.

Switches as follows according to combinations of SMR C/A bit of SCI0, SCR CKE0

and CKE1 bits, and the P32DDR bit.

If using as an SDA1 input pin, always set SMR C/A bit of SCI0 and SCR CKE0 and

CKE1 bits to 0 without fail.
