16-pin
Pin Number
Pin does not contain a clamp diode to V
The voltage measured on the internally pulled up RESET in will not be pulled
to V
IIC pins can be repositioned using IICPS in SOPT2, default reset locations are
on PTA2 and PTA3.
If ACMP and ADC are both enabled, both will have access to the pin.
