IIC pins, SCL and SDA can be repositioned using IICPS in SOPT2, default reset locations
are PTA3 and PTA2.
TPM2CH2 pin can be repositioned using TPM2CH2PS in SOPT2, default reset location is
PTA7.
TPM1CH2 pin can be repositioned using TPM1CH2PS in SOPT2, default reset location is
PTA6.
If ADC and ACMP1 are enabled, both modules will have access to the pin.
