1 _{The 20-pin package is not available for the high-temperature rated devices.}
2 _{Pin is open drain with an internal pullup that is always enabled. Pin does not contain a clamp diode to VDD}
and should not be driven above V_DD. The voltage measured on the internally pulled up RESET will not be
pulled to V_DD. The internal gates connected to this pin are pulled to V_DD.
3 _{IIC pins can be repositioned using IICPS in SOPT2, default reset locations are PTA2, PTA3.}
4 _{TPM1CHx pins can be repositioned using T1CHxPS bits in SOPT2, default reset locations are PTA0, PTB5.}
5 _{This port pin is part of the ganged output feature. When pin is enabled for ganged output, it will have priority}
over all digital modules. The output data, drive strength and slew-rate control of this port pin will follow the
configuration for the PTC0 pin, even in 16-pin packages where PTC0 doesn’t bond out.
6 _{TPM2CHx pins can be repositioned using T2CHxPS bits in SOPT2, default reset locations are PTA1, PTB4.}
7 _{If ACMP and ADC are both enabled, both will have access to the pin.}
