1 _{Pin does not contain a clamp diode to VDD and should not be driven above VDD.}
2 _{IIC pins can be repositioned using IICPS in SOPT1, default reset locations are on PTA2 and PTA3.}
3 _{TPM1CH1 pin can be repositioned using T1CH1PS in SOPT2, default reset location is on PTB5.}
4 _{TPM2CH1 pin can be repositioned using T2CH1PS in SOPT2, default reset locations are on PTB4.}
5 _{TPM1CH0 pin can be repositioned using T1CH0PS in SOPT2, default reset locations are on PTA0.}
6 _{SCI pins can be repositioned using SCIPS in SOPT1, default reset locations are on PTB0 and PTB1.}
7 _{TPM2CH0 pin can be repositioned using T2CH0PS in SOPT2, default reset locations are on PTA1.}
8 _{If ACMP and ADC are both enabled, both will have access to the pin.}
