1. Since the GPIOB[2:3] signals are shared with the XTAL/EXTAL function, these inputs are not 5.5 volt tolerant.
2. Schmitt Trigger inputs are: FAULTA0, IRQA, RESET, TCS, TCK, TMS, TDI, and TRST.
3. Analog inputs are: ANA[0:7], XTAL and EXTAL. Specification assumes ADC is not sampling.
4. PWM pin output source current measured with 50% duty cycle.
