20-pin 16-pin
Pin is open drain with an internal pullup that is always enabled. Pin does not contain a clamp diode to V
and should not be driven above V
pulled to V
IIC pins can be repositioned using IICPS in SOPT2, default reset locations are on PTA2 and PTA3.
TPM1CHx pins can be repositioned using TPM1PS in SOPT2, default reset locations are on PTA0 and
PTB5.
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. Ganged output not
available in 8-pin packages.
If ACMP and ADC are both enabled, both will have access to the pin.
